Hi, everyone I have come across a few coins that has yellowish oil on it, Correct me if I'm wrong but I have seen this on metals as well not just coins, I think it's used in cutting process I have seen this on aluminium and sheet metal, just saying this because I have worked with metals in a extrusion company. So it's not a dirty coin lol
