Good afternoon, here I am again almost 2 years later and not much more progress. I did have coin looked at Manchester NH Coin Show so I know it's real! I just really want to sell it now and hoping to find info as to what is the best approach? I really don't want to put a lot of effort into it since I am not a collector. Any advice is greatly appreciated.
I will let the real error collectors chime in. It looks real to me, but what I cannot understand is how a cent planchet could get struck in a dime press. Usually this error is a dime planchet struck on a cent press. Think about it, the cent is larger, how would it fit in the coller? Usually these coins are larger denominations struck on smaller ones, like a cent on a dime, a nickel on a cent, a quarter on a nickel, etc. Not the other way around. Pay a dealer to get it certified. If it comes back legit that will maximize your profit.
You went to the coin show. Did anyone make any offers? On the other threads you posted a few years back you were given the price ranges for such a double denomination coin. Just don't take the first low offer!
Here is what Mike Diamond said on an older thread concerning this Double Denomination - August 13, 2013
Then I would cede to anyone with more knowledge than I. Btw, I would have to agree with you that it appears this got some "help" at the mint. However, if the OP found it in circulation, its curious how it made it there. One would assume it went directly from the mint to a major error dealer.
I read that there are 2 types of Mint Assisted errors. First is that they create the Double Denomination, pull it out of the Die Press and keep it. The other is that they just toss a Cent into the bin with the different denomination planchets to get struck and it just gets lost into circulation to be found by a person such as the OP. If I find the article I will share it. And that a lot of these crazy Mint Assisted Errors happened mostly in the 1970's.. The OP's coin is from the 70's
This is the reverse from her original posting August 13, 2013 https://www.cointalk.com/threads/double-denomination.234731/page-2#post-1769675
I'm wondering.. Could this be an actual Cent on Dime? I think the color of the pictures the OP is presenting are off and we are thinking it's a Cent. So it's not a Dime on Cent but in fact a Cent on Dime. That would be more plausible!
With all due respect to Mr. Diamond; your recommendation was sound, particularly for a self-described non-collector looking to achieve the highest retail price possible. While arguably true that "authenticity is obvious to anyone with even a passing familiarity...", this does not automatically mean the coin will enjoy the same interest level, not only from error enthusiasts but also more generalized collectors, in its present raw state that it would top TPG certified. This certainly isn't to say that she could not or would not achieve a fair and/or reasonable price as is, but only that, as you stated, it would offer the best chance to MAXIMIZE the coin's potential.
