Since I just joined this forum.. I will list what I have found so far.
My parents own (well owned and now retired after almost 20 years) a restaurant. Over the last 7 years of it my family and me found the following:
1910S
Wheat centcountless amouts of wheat cents
6 rolls of wheat cents direct from the bank(oldest found was 1918P)
damaged
Buffalo nickel6 silver nickels
about 20 or so silver dimes
1945P&D quarters
1953D quarter
1954S quarter
1962D quarter
1964D 3x quarters
1995S proof (damaged through circ.)
Many recent Canadian coins, Mexican pesos (we live in south Texas so there is going to be a lot of those), an American sized quarter English coin, an Arabic coin.
Several $1 currency series dating from the 60's-80's
Binary note (eg 10110010 computer language for those you don't know what binary numbers are, can't remember the exact serial number though)
1934 series $10
1950 series $10
$20 with a serial number of X00003000B (X can't remember which reserve bank it came from)
1974 series $20
1969 series $100 (it was almost unc condition except it has a small tear on top)
Found in change:
several wheat cents
1943P nickel
1937D quarter (my dad would have probably spent this if I wasn't there to tell him)
From my trip to the bank:
1964 half (the teller had change out in a tray and I noticed a copperless edge half dollar, turned out to be a 1964 half)
I wished I had some banks here locally that have halfdollars, but then again I need a few hundred dollars to spare to exchange them, which I don't have.
I guess that's all I can remember so far. I don't have all of the money with me since I am at college right now and I left a lot back home.
