Ok 1st stage is done so will begin with the "before" pics followed by the pic after it was boiled in distilled water in a muslin teabag... it is now soaking in Verdi-care and final set of pic's should be up in about an hour or so... Even after just the boiling, I think you can see I picked a winner before... After boilinging...
here we go.. wasn't much to do after the soak... pics don't show it well but is a much cleaner brown then it was.. most of the particulate matter came off in the boil so actualy have a very nice looking coin on my hands... I'm happy
Best of luck! Coin is pretty much toast as-is, so why not? I haven't heard of boiling water as I try to gather up information for a crud pack 1856 Large Cent. It looks like you are up against so serious corrosion. Hope you bring it to a better stage.
These actualy show it a bit better.... final stage... PS. the off-roundness was from the background remover not the coins lol
Still has some really nice details despite all the corrosion, definitely is improved after the boiling process, I've only ever heard that method used by one other person, interesting...
