Electrolysis

[Victor]

I don't normally advocate for the use of electrolysis, but in this case I used it.

"This coin was in rough shape when I bought it. I could tell there was nice detail, but there were also many problems. There were a few red blisters where the corrosion was especially bad. I started with electrolysis, which was not removing the blisters of corrosion. I finally completely stripped it using a dremel with a brass cup brush. I re-toned it with Dellar's. The surface is a bit rough, but the detail is very sharp."

There are two other coins below it which turned out nicely also. Caveat...I have not included any pictures of the many coins that turned out terribly!
