I searched a bit of coin last night. It was so-so.

1 small dollar, 40 halves and 2,440 quarters had nothing.

1,600 dimes produced one silver Rosie (1953D).

1,360 nickels yielded one Buffalo (1923, date is extremely faint) and two Canadians.

3,850 pennies turned up eighteen Wheats, twenty-two Canadians, two US dimes and one Panama 1¢.

1911, 1931, 1934, 1940, 1940S, 1944(2), 1945(2), 1948, 1951D, 1953D, 1956, 1956D, 1957, 1957D(2), 1958D

Found: 3 pennies, 1 dime (a 1964D silver dime!), 1 quarter
