Counterfeits are imitative and therefore would have been struck on a gold flan. If not, it is a brass copy. There are no known contemporary counterfeits. There would not have been any gain from such an activity. At the time, the coin was not a circulating media and its only value was its gold content. Brass museum copies abound and are not intended to fool anyone as they are the wrong metal and weight and the die work is different that that of the originals. All the original New York Doubloons are punched with "EB" on the eagle's wing. One unique piece has the punch on the eagle's breast. If you believe you have a genuine Brasher Doubloon, you can have it authenticated at the American Numismatic Association. See their link on the CoinSite's link page for more information. Brasher Doubloons are very rare but didn't receive the attention they deserve until the 20th century. Recent sales(1979-81) at auction brought between $430,000 and $725,000. Name: Bill Ford Email Address: billford@azstarnet.com ------------------------------------------------------- Question: how much does light wiping and/or light cleaning detract from the value of silver coins. How do you identify this.
When a coin blank is struck by the dies, the metal becomes molten and flows into the recesses of the die and outward from the center to the rim. The metal flow lines are responsible for what we call luster. These lines sit directly on the surface of the coin and are easily removed. Any disturbance of the flow lines by cleaning is immediately detectable by an expert. Graders look for flow lines first when evaluating an uncirculated coin. Dipping a coin in silver cleaner reduces the height of flow lines because it removes the surface layer of the coin. The first time one does this the coin appears as if it has been improved but along with the toning you've also removed the protective oxide layer that develops on all coins. In a short time the coin "needs" to be dipped again. As little as three dippings can be enough to reduce the grade of a coin from uncirculated to AU. Excessive dipping eventually causes a coin to look flat and lifeless since it no longer has any luster. Even coins with obvious wear normally have luster. Even EF-45 coins will have luster in the protected areas of the coin. Once the luster is gone from cleaning, the uninitiated usually take to polishing the coin in desperate attempt to restore the coin to uncirculated condition (polishing is the process of moving metal). Polished coins are obvious to anyone accustomed to buying and selling coins. At that point the coin usually has been reduced to its metal value. Name: Ray Watson Email Address: tmrwatson@netzero.net ------------------------------------------------------- Question: Sir, A friend of mine has a coin that was presented to Rasmus S. Midgett for heroic deeds in saving the lives of ten men from the wreck of the Priscilla. This coin on the front has "UNITED STATES OF AMERICA ACT OF CONGRESS JUNE 20, 1874" with a picture of a rowboat and a man pulling another in. On the back is printed "IN TESTIMONY OF HEROIC DEEDS IN SAVING LIFE FROM THE PERILS OF THE SEA" Do you have any information that would be helpful in getting information about this coin?
There were standard Live Saving medals minted with a scroll where the recipients name was latter engraved. Some medals were actually created for a specific Life Saving event by Congressional decree. Note that the Metis Shipwreck which occurred on August 31, 1872 uses the motif of a man being pulled in into a rowboat. The original awarded medals were struck in gold or silver. Later on smaller versions of the medals were struck in bronze and sold to the public. The designs of this particular period are quite beautiful and no doubt because they were designed by the famous William and Charles Barber. I don't have historical records for the Priscilla but as an example the Metis Shipwreck medals would have been struck for the public around 1875 -1876. The mint records show 5,323 bronze medals struck in 1874 and 7,852 for 1875 and 14,348 for 1876. These beautiful bronze medals often appear in exonumia sales. Value Range:$80 - $150. Of course, if you manage to find an original it would be worth far more. (For example, the Metis Shipwreck gold medal contains 6.5 troy ounces of pure gold.)

Name: matthew t Email Address: mtcool10@aol.com ------------------------------------------------------- Question: I have some Eisenhower dollars. How can I tell if they are silver? I have a 1976 D and 1974 D. I read your page on the dollar and I know the Denver mint minted some of these coins. How can I tell if there's silver in one? Thanks
Name: Jim Petroff Email Address: petroff@prostaffing.com ------------------------------------------------------- Question: Is it a bad thing to soak a silver coin in acetone for several hours? Will this action cause a grading service to not slab the coin as "cleaned?"
Acetone won't hurt a silver or gold coin and it will dissolve many impurities that are sitting on the surface, like dirt and PVC residue. It will not affect toning (patina) or remove metal from the coin. You only need to rinse the coin in cool, clear water after briefly soaking the coin in acetone. Put the coins on a sheet of aluminum foil to dry. Do not rub, or blot the coins with a cloth or paper towel. Since the surface metal is not affected, this will not cause the coin to appear "cleaned". Note that acetone will not "cure" or improve damage already present from PVC or from previous cleaning. It is just a solvent. The coin may still be rejected by third party grading services. Comments: I really like the idea of publishing Stolen coins & currency Coins are much tougher to track but currency have serial numbers It really needs to be a searchable data base! I think ebay and other auction sites should REQUIRE that the serial number be in the description of any auction item. much easy to search a serial number my2cents: JUST remember, there are many of us that don't have the luxury of collecting GEM & CU !!! advertising the high dollar stuff really turns off new collectors! circulated is good! Name: aj Williams Email Address: aj@imtony.com ------------------------------------------------------- Question: Why is there a difference between Grading services if all grading services use the same grading guidlines? Even the GRAYSHEET defines a rating percent for each grading service, it almost sounds like the ground rules for 3rd party grading are not totally established. thanks PS: Can I clean my coins with three sodium salts in water and us a sable hair brush to remove rust! (does GOLD RUST?)
Grading is a art not a science. There is serious doubt whether anyone can consistently tell the difference between one grade number among eleven mint state grades (I'll admit I can't). This is a fantastic advantage for the grading services as collectors and dealers knowing that the grade assigned is subjective will pay to submit the same coins over and over again until they get the grades they want or need. Third party grading may survive because the current crop of U.S. collectors want guarantees that their coin is a specific grade. The only problem is that coins will decline in price as the grading services dilute each mint state grade. Eventually every collector will have to have his coins regraded in order to defend his investment. The only winner are the third party grading services. Comments: Very detailed! Name: David Email Address: WilDD85@yahoo.com ------------------------------------------------------- Question: Hi, I was wondering if The American Historical Society is a good company to order coins? If so, is a 27 coins set of the coins from the 20th century worth buying from them? Thanks for your help.
From: Bill & Bonnie Subject: Old German Currency I have resently aquired some german currency that according to my bank is too old for an exchange and I was wondering if it was worth anything to any collectors? I have a 20, 50, 100, 1000 dollar Reichsbanknotes. The oldest is printed in 1908 and the newest was printed in 1919. I also have a Reichsbanknote for Funkig Millionen Mark printed in 1923. This is a one sided note and all the others are two sided (like a us bill). They are all in very good condition and easily legible. I dont know if it is worth anything or not. Maybe you could help or direct me to someone who can help me. Thanks for any information. Billy
There is a system of grading bank notes and this information has a strong influence on price. For an example a 1914 Germany 20 Mark dated 5.8.1914 [August 5, 1914] with 6 digit serial number in VG (very good) brings about 25 cents. The same note in uncirculated condition (new) brings about $175. The AGE of the note has no bearing on value (some asignats from the French Revolution sell for $5). Only rarity, condition and collector interest are significant. Name: Pam Email Address: babynurseprn@hotmail.com ------------------------------------------------------- Question: I have an old coin that is a commorative coin of Ulysses Grant........I have had the coin over 30 years now, and it was given to me by my Aunt who had had it for a very long time.....any ideas on its worth?
There are two varieties, one with a star and one without. The star has no particular meaning but it made collectors want to buy two examples (Mint marketing at its finest). The coin is usually seen in About Uncirculated to Gem uncirculated condition. The coin was sold at a premium and never released for general use. Value Range with Star (AU - MS65) $500 -

Could this be real or someones science project? I have not weighed it and I do not know if it would be lighter or the same 3.11 grams as a regular penny. Did the Mint experiment with aluminum in the early 80's due to the price of copper then? Thank You, Keith
Comments: ONLY place I could find some answers!!! Great site! Name: Tim Christensen Email Address: tim.christensen@juno.com ------------------------------------------------------- Question: In archive #12 you answered a question about a silver Massachusetts coin which was a reproduction of a copper coin. Mine isn't silver. I don't know if it's really copper or not, but it seems to be, with a patina on most of it. The edges are quite rough and it is not perfectly round. It does not have the "copley" stamp in the corner of the reverse, as the (some?) copies from them do (reference http://www.coins.nd.edu/ColCoin/ColCoinText/StatePatterns.1.html). The lettering does not have serifs on it as the picture at the website above does, but does closely resemble the lettering in position and size. The globe on the reverse is also slightly different than the copy on the website above -- the longitude lines don't converge the same. (There are the same number, but they just don't quite look exactly the same.) The coin in my possession (actually, my daughter's posession) has a history... Her great-grandfather gave her the coin about 2 years ago. The story he told her was that when he was 11 or 12 years old, a friend gave it to him because he didn't want it any more. He was born in 1903, which would make the date that he came into possession of it around 1914. He kept it in a coin box for all those years until one day my daughter was asking some questions about his collection and he gave it to her because she thought it was interesting. My questions revolve around whether it's at all possible that the coin is authentic.... were copies of the coin made as collector's items before the 1910's (when great-grandfather got the coin)? Would even copies of that vintage have any value? How can we find out if it's original? (Very unlikely, I know.) Is the only way to send it to the ANA? How do you protect the coin? Do you insure it? Thanks for any help you can provide!
The Hobby Protection Act passed by the United States Congress some years ago requires that coin reproductions have the word "copy" or "replica" stamped into the reproduction. Of course, replicas made before the act have no stamp. Many of the old reproductions were made about the time of the centennial celebration in 1876. These and other colonial era replicas were sold as souvenirs of American history. Replicas, even old ones, may have no specific value. If you would like a definitive opinion, send the coin to the American Numismatic Association for certification (see the Links page for the ANA site). Comments: Easy to navigate. Name: Nadine Email Address: nxtucke@uswest.com ------------------------------------------------------- Question: My son was told by his teacher that the Connecticut Quarter with a tree on it was worth $50.00. Is there any validity to this?
Occasionally, errors are found. There is a popular collector market for these. Most errors will bring a premium over their face value whether they are State quarters or any other coin. Please see the "What's it Worth?" feature. Comments: GREATTTTTTTTTT!!!!!!! Highly informative. nobody gives staight-forward and concise answers with histoical explanations like you do!! Name: Daniel Mackey-Stephan Email Address: djmackey@msn.com ------------------------------------------------------- Question: Question (1) What is "notgeld" my knowledge of german tells me that it means 'emergency money'. what does THAT mean? (2) Where can I find coins for sale "Deutsch Kiautschou" ( German Kiaochow ). were all coins from this region (and time) minted in the same year? I believe only two coins (both copper) are available?Thanking you in advance...Daniel Mackey-Stephan
"Notgeld" translates as "Necessary money" so as not to upset the authorities. This is very much like the emergency tokens of the United States Civil war that were labeled "Not One Cent". Notgeld was used in many German towns and villages during and after the great inflation of 1923 in Germany and Austria. There are a lot of issues and they were printed on a variety of materials including porcelain and leather as well as on paper. Unfortunately, if you visit some of the towns in these areas they are still making the stuff and selling it to the tourists. Since there were few if any security devices on this token currency, they are easy to reproduce, therefore few of these issues are worth more than a nominal amount.

Name: Beth Vinoski Email Address: TEDDYBEARS@COMPUSERVE.COM ------------------------------------------------------- Question: HI! I've been searching the coinsite.com website for some time now, and I was hoping you could help...I have an 1849 Twenty Dollar coin from the Cincinnati Mining & Trading Company and I am looking for any information regarding it's worth (if anything), and if there are any collectors you may know of who may be looking for this particular coin. Any information you could provide would be greatly appreciated. Kindest Regards,
Only one $5 gold piece is known to exist and the $10 gold pieces are very rare (last auction price: $200,000). There are many replicas in base metal, brass or white metal, that are either museum copies or made for some other commercial use. A well known copy of the $10 coin has the word "TRADING" spelled as "TRACING". Copies have no specific value. Comments: very informative keep up the good work!

They are 20 francs gold coins, stamped in the 1850-1860 with "Napoleon III Empereour". Also Russian gold 10 Ruble coins stamped in 1899. I look forward to your response. Thank you, Mihai
Comments: I just found it! Will see if it responds back! Name: A. Barcenas Email Address: angandmig@aol.com ------------------------------------------------------- Question: I have a penny from 1958, which looks like silver. How can I know if this coin is worth anything? Is it worth something?
1. A cent struck on a dime planchet (blank).
A silver dime blank (dimes were silver until 1964) got mixed up with the
cent blanks. Since a dime is smaller than a cent, the main characteristic
of this error is that the outer parts of the design are missing.
This error is quite scarce. Value Range: $200 -$300. |
