Are my PCGS coins ruined?

Swamp gas , maybe ?

I wouldn't use any that have been in use for protecting any product as they might contain contaminants . Just to be safe I buy the reusable ones with the aluminum holder and clear hole to see if the beads need recharging . Also you should change them a lot more often . I find mine need recharging at least every month or two and I have 3 desiccant packs in about a 1/2 cubic foot of air .

 

If I recall correctly, milk spots were covered under the guarantee at one point, but it was retroactively amended, so it appears that they reneged on that too.

 

That was my thought too, but someone from NGC posted on their forums at one point that toning lowered the grade on a coin from MS/PF 70. I'll try to look it up.

 

isn't collecting a witch.

 

The problem is revealed in the first line of the OP's post. Buying PCGS 70 ASE's? There's the problem right there. There is no more certain way to lose money over time than with that formula. That formula is DESIGNED to extract an "ignorance tax" from the first buyer.

 

Uh...no http://www.fsis.usda.gov/wps/portal...sheets/safe-food-handling/packaging-materials a really quick test for halogen (chlorides) containing plastics is to heat up a copper wire in a cigarette lighter flame and touch it to the plastic while still hot so that it melts some plastic. Then return it to the flame and look for a green flame.

 

Cedar and mothballs...I really hope you are joking, this would be a recipe for disaster. I think the toning would be interesting though.

 

I have been thinking about using molecular sieves for combatting moisture. Have to look for somewhere to buy them cheaply instead of just lifting them from the lab. You can regenerate these in a microwave oven.

 

Actually, if you know what you're doing, this is an excellent idea!
