I would too, Cheech. I have a roll set, by year/mm. I don't recall if I have a full roll of 1972 S, but if the roll is full, I have them stacked from best to worst, worst being towards the top. This way when I find a nice one like that, I can replace a worse one with a better one.
Not a proof but that's one clean copper memorial cent for a circulation find even if it is a business strike frisco,keep that one safe.
