This is probably a stupid question, but some of the sets I'm looking at have coins that have a PL deduction. PL stands for proof-like, right? Why would that warrant a deduction? I would think it would be a bonus. Or does it mean you get a deduction if it's not PL? What am I misunderstanding? Thanks.
