This coin is actually the first ancient coin I ever attempted to clean. The coin was so heavily encrusted that there was absolutely no way to get this off without major intervention. There was a very fine patina underneath everything, which made me set this aside for cleaning. At the time, I had no idea what to do, at all. I just mixed up some sodium hydroxide and dunked this in the solution overnight. After the chemical dunk, I failed to actively mechanically clean any part of it, leading to a rather nasty, pitted, and oxidized appearance. Not knowing any better, I applied a bunch of green, and black Jax Patina Restorer, and slopped some Renaissance Wax over it. This led to a very uneven appearance, which was rather unattractive. I left the coin in this state for 6 months, until now, when I decided to try again with my new wealth of knowledge. I decided to strip the coin as much as possible to even out the end result for a (hopefully) more pleasant appearance. This time, my method was as follows: 1. Sodium hydroxide dunk to remove mineral encrustations. 2. Vinegar to remove blue/green oxides that showed up. 3. Mechanical cleaning to get most of the minerals off. 4. Sodium thiosulfate to get rid of the reddish brown iron oxides. 5. Final mechanical treatment 6. Jax Black Patina 7. Ren Wax Despite the rather brown look in the pics, in-hand it looks much darker. I think my new result is pretty nice. What are your thoughts?
