How much do you think a 1951 proof (proof-66) dime would be worth? Only 57,500 were proofed that year? I recently ran into a deal were I could buy one off of eBay for $50.00 Is that a good deal?
Proofed? Grey Sheet for a 1951 Dime in PF-65 is $40/$44. $50 doesn't sound out of line for a PF-66 (if the coin is actually a PF-66 and not some third world slab graded PF-66).
