1979 Lincoln Cent Struck On Dominican Republic 10 Cent

Absolutely amazing! I can't comment to value - in a case like this I usually look for YOUR valuation.

Congratulations on this.

eBay...few years back. Bought raw as struck on U.S. dime planchet.

Are the Dominican 10c pieces produced from clad planchets, or alloy, and is the wight/size different from a US dime? I definetely wouldn't have noticed it as being struck on a foreign planchet. I took a quick check at the HA archives and there were two modern examples like yours, but the price variance was pretty great -$350 and 700 -and they were mid-mint state examples.

Wow

Great thing to keep in mind for selling.

Which brings me back to wondering, how would one put a value on vermontensium's coin. As an error collector, what do you think about when you come across a unique item like he posted? Is there a method to your madness in figuring out what you would pay?

Little did I think that when I joined CCF that I would have to get off my ____ and do some research to help educate both myself and the poster.

In this thread I could not let this go without looking further into how this error occurred, and after dusting off the cobwebs on both the 1999 edition of Krause World Coins 20th Century and Coin Worlds ALMANAC "(Millennium Edition)" I found the following;

To answer ErrorCoins222 question on the metal composition, Krause lists the 1979 Ten Centavos on page 204 as being minted on copper-nickel planchets with no mention to the size or weight, and now both of us know it was not struck on a clad planchet. If this was my coin I would call it a Lincoln Cent struck on a Dominican Republic wrong planchet error as it was struck on a Copper-Nickel planchet instead of the 1 Centavo Bronze planchet. Krause also notes that in 1984 the 1 Centavo composition had switched to Copper Plated Zinc (can we assume the US Mint struck some of these also?).

Now to find out how this error came about, I checked out the Coin World Almanac for Foreign coin production in the U.S., and on page 429 is a list of the Countries the Mint struck coinage for from 1875 to 1984 and Dominican Republic is listed. There is also a yearly production mintage of Foreign Coins struck by U.S. Mints, but does not give a breakdown of the Country/Countries by year, only the total mintage production for said year, and in 1979 total output was 15,530,090 pieces.

Case Closed

FWIW, Numismaster lists the Dominican Republic 1978-1981 10 Centavos as 2.56 grams and 17.9mm in diameter. That would make it a bit heavier than a US dime but CuNi alloy would also be harder to strike than CuNi clad with a copper core.
