Questions About Proofs

Jaobler - sounds like I need to get out to some coin shows and get me some of those BU "proofs" - hehe. Thanks for the answer. As I got to thinking about that question struck me. biokemist6 I will look around tonight and see if I can't pick that book up. Does it cover the details like the different reverse dies used ans such? I assume it probably covers things like errors as well. Again guys this has been a lot of fun just learning this stuff.

I just checked a 61 P that I bought a while back (one of the ones that got me started) IT was advertised as a GEM BU that was from a mint set, however it has the B reverse. So I either have one of the business strikes with a B reverse or I have a Proof that was though to be just an uncirculated. Now in comparing this 61 p to a known 64 proof the only difference I see is that Washington's portrait in the proof does not carry the mirror finish that this 61 does so I'm inclined to think what I have is a 61 P Business strike that was struck with the B reverse die.
