OK, here is a weird one. 1940 Quarter does not have a mint mark.

Here is another 1951 Quarter and it has a Dever mint mark when research says it should not have one.

Hi, Annjeanette --

A 1940 Washington quarter without a mintmark was made at the Philadelphia Mint. In 1951, the Denver Mint made more than 35.3 million Washington quarters. Here's more info on both the 1940 and 1951 quarters:
