Tried cleaning an old Roman coin with olive oil like a YouTube video said
I found this bronze coin at a local field near Chester last spring and thought I'd try the whole olive oil soak method I saw online. Let it sit for like 3 days, thinking it would gently lift the dirt off. Instead, the oil just turned into this nasty green sludge and when I wiped it, half the patina came off with it. Learned the hard way that bronze coins from the 3rd century are way more fragile than those videos let on. The coin is basically ruined now, just a blob of metal with a faint outline. Idk, maybe I should have left it alone or asked someone at the local museum first. Has anyone else messed up a find trying to clean it at home?
