Just wondering what (if anything) some coins are worth? I have some Kennedy Halves from 1965 and 1967, Some Eisenhower dollars from1971 and 1974, some quarters from 1934,1940 and 1945. also some from 1965,79 and 80. also bicentiniel quarters and halves? any help would be appriciated. Oh yea, What about wheat pennies? what should I look for in one that is rare? Thanks
