[QUOTE="robinjojo, post: 4529964, member: 110226"]I came across this coin, purchased as part of a large lot of Byzantine bronzes about two years ago. The reverse field seemed odd, especially regarding the color. Also there were incipient indications of bronze disease, so into the distilled water bath it went last night. This morning, after looking the coin over, I decided to give it a soak in acetone. There seemed to be some kind of resin used on the reverse. I was right - the acetone almost immediately dissolved the resin, or lacquer, and loose earthy material came off the coin as well, leaving two depressions, which appear to be either flan flaws or punch marks of some sort, or possibly spots of corrosion. The coin is back in the distilled water and will remain there for several weeks. The second photo was taken with a flash, so the light and color is slightly different from the first. Well, at least now it is an "honest" coin. 8.5 grams Before: [ATTACH=full]1121990[/ATTACH] After: [ATTACH=full]1121991[/ATTACH][/QUOTE]
