Anyone can see that the first 6 differs in shape and design than the first 6, also it matches the 5 on the date of the 1865 two cent ....
okay, you win. [happy? but, I don't mean it, I guess that I am not "anyone who can see"] Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book. Buy the book.
If it were not for newbies coming here and seeing post like this I wouldn't even bother responding anymore to OP post. However they are coming here and I don't think it would be wise just to ignore these post with images posted and misinformation. This is a normal 1866 2 Cent piece. I see nothing indicating an overdate. OP, Please keep in mind that coins were minted differently in 1866 than they are now. I will say its not a bad looking 1866 2 Cent piece though.
plain and simple over dates and doubled dies are not super common. yet every single coin you find is one of the two. you would have to be the luckiest person in the world. take time to truly learn about the errors instead of posting so many coins that are obviously not errors.
It's not MS and there is nothing special about this coin. If you keep this up, no one will reply to your threads. Everything you post is false information.
Yes, there is a slight difference, but it is not an overdate. I can see the point of confusion by the statement I believe you mean "second" rather than using " first 6" again, but it seems you think that because the 6 matches a 5 of the 1965 coin, that it is a over date. The dates were punched into the dies using a gang punch which had all 4 digits of the date arranged on a holder to strike in the date. A "6" from 1965 could have been combined with a different appearing 6 for your 1866 coin, that would be normal as the date wasn't on the master die. It would take evidence of a "5" beneath the last "6" to make it an over date. Although it doesn't really matter, the last 6 in your coin seems to have some date die deterioration to cause the difference.
doubledieking18, I consulted my copy of "The Authoritative Reference On Two Cents Coins", Copyright 2011 by Kevin Flynn where three 1866 repunched date varieties are illustrated. Unforunately I am unable to confirm any definative match to your coin due to the pic quality. Repunched date digits are quite commen in the two cent series so you haven't hit a jackpot. In line with the advice above I would recommend Kevin Flynn's book, where with the coin in-hand and with proper magnification you might be able to confirm which of the three possible varieties you possess. Good Luck
