I have a 1976 Eisenhower dollar bicentennial dollar type 2 with liberty bell on the reverse with thin lettering and has no mint mark and is clad.I believe it is a proof coin.Because it has no mint mark is this a coin that was minted in Philadelphia for circulation or a trial coin that were made at one time .Because Philadelphia has no mint mark and the S and D coins do how do i know what i have could it be one of the rare Ike coins or not.
No mintmark appeared on Bicentennial Halves in 1976 so yours was minted in Philadelphia. It's not a proof. It's a business strike intended for circulation. Welcome to CT.
No es verdad........they did. But this one is is an Ike, and they were issued with mintmarks (other than Philly).
