Cheap Silver State Quarter Proof Sets

All the sets can be had at just above melt except for 1999, 2001 & possibly 2002. I'd break them out of OGP anyway because I don't think the volara foam used in the holders is that archival. If they are stored at higher than average temperatures, the volara tends accelerate the edge toning. Notice that the 2010 and later sets have the coinedge style plastic holder.

I havent seen anything in any of my sets to support that. When you say higher than normal temps, what do you mean? I cant imagine anyone storing coins in a way that exposes them to 90 degreee plus temps for any length of time.

@smokeriderdon: You must live in a climate with low heat and low humidity. I lived in Florida in the early 2000's and when I went on vacation during the summer one year for three weeks I turned off the air conditioner, not thinking I needed to keep my coins cool. It was a very hot summer and the house must have gotten into the mid-80's for a few hours every day. I had a few silver sets including several white, pristine 1999 sets in a box on a shelf, and when I looked at them after my return most of them had a ring of champagne toning along the rims. Not unattractive, mind you, but they were white when I bought them. This is primary reason that accounts for the toning of modern silver sets. The warning the mint sends out appears on every COA: "To preserve the beauty of your coin, store in a cool, dry place." I didn't think it could personally apply to me, but it happened. Every set I've bought since then I've removed from the OGP as a precaution and placed in Air-Tites, and have not had that problem again.
