One sided Dip Method
What method do folks use if 1 side of coin has unsightly or worse, potentially damaging toning, but the other side is clean or has decent toning one doesn't want to effect. Talking about an MS coin. I've read of the Q-tip approach, but do not like idea of leaving dip acid on coin for more then a couple of seconds. Would think lightly rolling the Q-tip to not leave hairlines but do the job would take time, 10 seconds or more, to effect wanted results. Not talking about that minute spot treatment but an area that effects say 1/4 of a Morgan side.
Of course sell and buy another is an option but not looking to go down that path. Trying to improve what I have & more about stopping any potential future issues down the road.
Thanks for suggestions.
