UPDATE: Yesterday, I received my cleaning chemicals from my new best buddy Mayadigger AKA Kevin from Noble Roman Coins! Evidently the USPS and US Customs intercepted my first package that Kevin sent me and they completely DESTROYED everything in the package! It was cut open, the #1 bag of chemicals was EMPTY, the rest were cut open also and the contents mixed together in the main envelope and on top of that, my tin of wax was stolen! (I can only hope that the lye in the #3 pack burnt the bastards!) :crossfingers:
Kevin had already sent a replacement and I got it on the same day! I can't sing enough praise for Kevin's customer service! Thanks Kevin!
Anyway, I soaked this medallion in the #2 for 12 hours and it did a great job of cleaning this item!
Now here's the question: This item is not metallic and has a bright silverish color. However, the encrustation is cleaning off BROWN, like rust. Does anyone have an idea what type of metal this could be?
