I purchased these coins but never realized they were proof coins. Well, I knew the 93' was proof. Do they have any extra value over regular non proof silver coins? In their condition what do you think I could get for these 3 together?
They look to be impaired proofs (not perfect as they were intended). I'd say they're worth about what any junk silver quarter would be worth.
Provided they each graded a minimum of Proof 65, current catalog value is around $50.00 for all three but what you could get would be whatever someone was willing to pay you for them. Nearly impossible to grade them through the holder you have them in though so it would be wise to put them in separate flips to prevent any damage to the reeding. (edges)
