Ok so the draped bust large cents were minted in 1796, 1797, 1798, 1799, 1800, 1801, 1802, 1803, 1804, 1805, 1806, and 1807. There are 2 hair styles. 2 curls, and 3 curls. On 2 or 3 of the coins I can see that they are the 1st hair style, so I know that those coins are 1796, 1797, 1798, or 1800 (80 over 79) and the rest are unidentifiable. So I have been able to identify a few of them, and I know what I'm looking for.... But these coins are so far beat up, getting a date off of it would not ruin any sort of value, only help it.
All I'm asking, is there a way to get dates off of copper coins? Like for example, useing "acid dating" like we do on nickels. I'm not saying that acid dating will work for copper coins, but is there a tecnique like that, that I can use. Sorry if I wasnt clear the first time I posted. Ill try to post pictures in a bit.
