| Mintmarkless proofs
Hey ericl...Yep, I realize there have been beaucoup incidences of various coin denominations throughout the years having been struck mmless proofs. My question specifically was directed at those coins that were struck as mmless proofs prior to the year when the Philadelphia mint began marking it's issue (ex. 1971 Jefferson).
The gist of my question was how would one distinguish a mmless proof that has been in circulation for 3-4 decades from a business strike of the same year, minted at Philly before the Philly mint began marking it's coins.
Admittedly, I'm pretty much a novice inre coin collecting. However, I assure you, if I come across ANY "silver" or nickel US coins minted post 1980 that lack a mintmark, I'm going to spend some time studying that bad boy fer sure!
Thanks for the info.One thing I have discovered since being snagged by the collecting thing...The more I learn, the more I realize how little I knew. Thanks again.
