Some vendors sell rolls of proof coins. Where do rolls of proof coins come from in the first place? The mint doesn't sell them.
dreamer: they come from the deaths of many, many individual proof sets. Listen carefully-- oops there is the cracking of another proof case.
Example, L&C coins always sells rolls of proof coins. They also sell more PCGS PR-69DAM singles than anyone. You think the proof rolls have been cherry picked? Hmmmmm I always have wondered about the proof rolls myself too.
Proof coins do not normally suffer any damage in being busted out of the sets and rolled. Most of these are cherry picked but most of those cherry picking remove more dogs and culls than cherries. This means the average quality of these rolls is better than the average quality proof set but the range is much narrower.
You can tell from my questions that I haven't bought a roll of proofs. Do people usually at least take care to handle them with gloves so they don't get fingerprints? It surprises me that being put in a roll doesn't damage them, but you learn something new everyday! (I'm sure it's better than bagging them!)
When you joined Cointalk did you bother to read ANY of the rules? Stop pushing your auctions - PLEASE! I appreciate your efforts, but it would also be a good idea Clembo if you didn't copy the the rule breaking post thus doubling the infraction.
They'll either wear gloves or refrain from touching the faces of the coin. Fingerprints can form very quickly on proof coins so touching them will lower their value. Gloves are a good idea but just frequent handwashing and handling the coins by the edges will take care of 99% of the problem with skin oil. I'd imagine it can be tougher to protect them from sneezes and other air-bourne pollutants.
