Is there anything I can do to arrest or reverse the process? This coin was pristine about 15 years ago. Now I'm seeing a small spot behind Washington's head and also on the right wing of the eagle.

a soak in pure acetone is the usual recommendation, however in this case I'm concerned the white spots (mold?) have etched the proof surface, in which case the acetone might remove the white, but make the potentially scarred surface more visible
since this is a meaningful coin for you, I'd first try such an acetone soak on a lesser proof coin with the same symptoms to see if it turns out better or worse, and after that keep the coin in a drier environment than before

This is the only one I have like this. How long do you do the acetone soak? I know to gently pat dry following that and not to rub the coin at all. I know the coin is not valuable, but it does have some significance to me.

as long as it takes for the grime to release, but after a few hours little more is likely to come off so you might as well stop
use pure acetone available from hardware stores, not nail polish whicht has damaging additives, then rinse briefly with clean water, shake off any droplets, and let air dry
if you try it, may your coin turn out well, let us know

One small comment - I usually follow an acetone soak with a quick rinse in fresh acetone and then simply let the coin air dry. The acetone evaporates very quickly with no residue. Just use it in a well-ventilated area. And, there's really no need to do a water rinse afterwards.

Thanks. I will give it a shot this weekend and report results.

OK, just put the 1956 into an acetone bath. Figured I'd give it 15 minutes. Good?

Will a longer soak help this out, or is this about all I can expect?

Does Verdi-chem do anything salutary to silver coins? Trying to learn and appreciative of knowledge imparted.

if you've soaked it for 15 mins so far, you could probably try a second saok for an hour
most gunk comes off within the first couple minutes, so an hour soak will probably make only a small difference
don't forget that every time you handle a coin, you run the risk of damaging it by accident (dropping it, leaving a fingerprint, etc.)

Thanks, I'll give that a shot. I can see an improvement from the 15 minutes and the coin really has no value except on a personal basis for me. Trying to improve the appearance of any coin is tough for me as I was always told (way back when) to just leave them alone.
