That's really cool!  To my eyes, there almost appears to be something under the Memorial reverse--or just damage?

Quote: Hopefully there will be 2 or more people that really want the error. 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?

Are the Dominican 10c pieces produced from clad planchets, or alloy, and is the wight/size different from a US dime? They're CuNi, and lighter than a dime. That's how he knew it wasn't a US dime. The thinness of the planchet is what caused the incomplete strike. Quite frankly, I'm curious how the Heritage coins achieved that much better a strike - there really isn't enough metal in the planchet to fill the details unless the press is allowed to move deeper into the planchet than they'd set it for Cent mintage. Then again, that's how clashes happen, so then I wonder why Dave's coin wasn't a better strike....

 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

@SsuperDdave As we don't know the weights and size of the Dominican Republic errors, I can only make a educated guess (and I'm not good at guessing), but maybe what I posted below may help explain the strike weakness as the heavier planchet received the stronger strike. Below are 2 @ 2003 Costica Rica 25 Col. (?) errors that were struck on Foriegn Planchets (not Costa Rica planchets), both with different weights, and maybe something like this happened with the Heritage coins you mention.

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.

Thanks so far everyone!
Bob, FYI, it weighs 2.41g.

Interesting, Numismaster.com is operated by Krause so I will have to check my Standard Catalog of World Coins to see if the website listed an erroneous weight.

Cool. I wonder, could ANACS have gotten it wrong?

The actual 10 Centavos, as struck, indicates 2-1/2g on the coin itself.

For the record, this is the third 1979 so identified by ANACS. If there's one, I would logically expect others. This one shares the grade with one other - none finer - which I suspect is a function of a strike which can never be complete enough to actually grade.

NGC has graded a couple - problem free. They were on HA.
