The idea is when your searching roll's whether you bought them off the internet or went to the bank to purchase coins. Circulation is very vague when it comes to my question: Coin's that have been found in a circulated enviroment. Mine is the 1936 Coneca Listing 1-0-IV and Coppercoins listing 1DO-001. This hobby is very interesting. What brought your interest into collecting coins? Rhubarb
It would seem the most valuable coin I've found in circ is a 1990D Kennedy with concentric portrait lathe lines. According to this thread ( http://www.cointalk.org/showthread.php?t=10675&highlight=concentric+lathe+lines ) it may have a value around $25. I also got a solid date box of 2000D Kennedys with the same effect on +50% of the coins, though not nearly as distinct and so I'm not yet sure any of them have value above face.
1909 S VDB in about Uncirc condition. Nothing really big though since that was in about 50 or more years ago.
Back in my cashier days I found an 11-S Lincoln in F. Also found a 14-S in G. My BEST finds, by far however, were in currency errors.
1922 peace dollar loose from the bank with 12 walking liberty halves was my all time best 2 years ago
I got a 1944-D Mercury dime in change this summer. By my reaction, you'd have thought I won the lottery.
