The oldest I ever found was the one that initially got me into coin collecting many years ago...around 1956 or 57 I found an 1864 Indian Head Penny in change, took it to a coin store and he gave me $5 for it...must have been the "L" variety and it was in really nice condition...nothing with that much of an age spread since though last year I got a 1916 Barber dime in change, in about G condition, very worn.
