Here is an interesting coin that I ran across recently (did not win). It is in an old Hallmark slab and a much better date than one normally sees in a non top 5 (PCGS/NGC/Anacs/ICG/CACG) holder. Hallmark called it PQ and it has survived in the old holder. If you were trying to price this coin, what would you do? Based on the photo (that is all I have), would you consider it PQ for the grade, acceptable, or overgraded? And how would that impact your pricing? Here are some guide numbers from Heritage as a reference
Does “PQ” mean “Proof Quality”? An obsolete term for “Proof-like” (PL) maybe? Looks like it would walk the walk in a crossover, to me, it’s an excellent coin. MS63+PL.
I would reason that PQ means 'premium Quality,' an old Paul Sims trick at grading. Judging by the photog, I'd hazard the coin itself is undergraded.
