Do TPG's stabilize a coin's surface before slabbing it?

Do they soak a coin in acetone or any other treatment? I'm just curious because if they grade a coin and then it develops unattractive spots or toning in the slab because of a foreign substance on the coin, it might not reflect well on the brand.

Need a Barber Half with ANACS photo certificate. If you have one for sale please PM me. Current Ebay auctions

    No. Many wouldn't send them coins if they knew they were going to mess with them.

    Worry is the interest you pay on a debt you may not owe.

    Lol, no. Old school conventional wisdom is to not mess with a coins surface in any way. Coins will be slabbed exactly as they are submitted unless you submit for conservation. I personally rinse the majority of my new purchases with acetone, at the very least. I don't know who had them before me, or how they stored them, or what they may have put on them.

    No, too much risk and introduces a bottleneck in the process. Also there is additional liability involved and someone would claim the process damaged something.

    Can you imagine the liability?
