I'm not sure if this mist isn't sometimes already caused by a change in temperature or humidity if you take a coin out of an air-tight holder.
BTW does anyone use one of those and are they any good?  |
The mist he mentions is caused by temperature change - your hands are warm the coin cool - condensation can form where you fingers touch the coin. In 45 years - I have never seen this while wearing gloves - ever. Apparently NOS has.
Coins should be stored at fairly consistent temperature - room temp if possible. And abrupt changes in temp should be avoided.
As for the coin tongs - I would not suggest them unless you like dropping a lot of coins.
