It would be helpful if you discussed your methods. It’s hard to tell exactly what you are dipping it in and how long. Also, do you plan to submit this after you finish?
Hopefully, you're doing this to test a method. Otherwise, you're spending a bunch of time to add $0.25 in value. The rim on the obverse from 5 to 8 o'clock look very concerning. It will limit the value to under a buck.
Yes I am the coin means nothing lol I wouldNY of cleaned to begin with cause red spot already existed on back
The red spot, looked like something (organic) that acetone would remove. Currently, the color is leading towards looking cleaned. It seems yellowish.
