Found a 1981 S proof set at my local pawn shop today. The penny has some sort or corrosion on it, not sure what that's about being in the hard plastic cases, but, the rest of the set is in BEYOND perfect condition, no scratches, dings, they all look like mirrors and look brand new. I really cant tell of any of them are type 1 or type 2 but I can clearly see the "S" perfect and plain as day on every coin, no blobs, but can't be 100% sure due to waiting on my scope to come in. That being said, are any of the coins in the set worth getting graded. I'm hoping the penny doesnt cause any big problems with the set. Thanks in advance.
