[QUOTE="Orange Julius, post: 3539209, member: 77226"]Quick question to the group... I have this Victorinus that's been sitting in a jar as a "give away" or "sell" coin for years. It was struck by a very worn reverse die but it's still not a junk coin. I ran into it today and wanted to take a run at removing the green encrustations on the obverse. Under the green is smooth coin, not corrosion. The encrustations are too strong for mechanical removal without gouging the coin itself... so I was hoping to get some recommendations for soaking it in something a bit stronger than distilled water (this coin sat in DW for 6 months a few years ago with no success). I've seen acetone, vinegar, lemon juice... and others as possible solutions. Anyone have experience with removing these types of encrustations? What works best without pitting the coin or stripping the patina? Thanks! [ATTACH=full]940560[/ATTACH][/QUOTE]
