Last night I didn't search too much.

2,040 quarters produced two Canadians.

300 dimes had nothing.

120 nickels had two Canadians.

750 pennies yielded five Wheats (1942, 1947, 1950D, 1956, 1956D), four Canadians and a US dime.

A teller saved me four Wheats (1940, 1945, 1946, 1955).

Found: 1 nickel (at Stop & Shop), 1 dime (at Stop & Shop)
