If those were LIncoln CENTS. I would crop some of that picture. Then hang it somewhere. Did you spell that with memory?
Not sure if you’d know this but since you’re a chemist; would xylene ruin ANY kind of coin? (Gold, copper, silver etc) because I want to clean up some various coins in my collection but want to be safe first. One is an over struck 20 cent
Thank you, they are Daniel Carr Halloween Medals. He made 36 proof and 74 satin pieces. Another mint bought 30 of the Satin pieces and had them painted. There are a couple on Ebay, not mine of course.
Pure solvents such as water, acetone, alcohol (all kinds), toluene and xylene won't harm any metals...not so good for pressed paper tax tokens though main warning though is soak and rinse...DON'T WIPE OR RUB!!!
This is my "ghost coin" - you can see the impression that the coin made on the OGP plastic, as if the coin was the die and the plastic was the planchet:
Some say yes, I say no. Rinse with the same solvent you used for soaking. Acetone and lower alcohols mix with water, so a water rinse will remove them, but the water is more likely to cause damage than the remaining solvent. These solvents also evaporate faster than water. Best just to let them evaporate. Xylene doesn't mix with water. A water rinse will physically knock it off the coin, but won't necessarily get all of it. Again, I think it's better to let it evaporate/drain.
