Okay, forgot how to read archived answers, but I really need to remember the cleaning buffalo nickels thing!
Six months later, and who know's how many buying and selling activities later etc, now I'm back to my original question. How can I clean a dirty Buffalo? I bought about eight off this person, all just dirty as all get out but early twenties and you could tell their are mintmarks and good detailing (horn's etc.) under the grime, so for me to do anything with them...most likely just sell them to reinvest in Morgan's, I need to cut through the grime without risking them not being grade ready for either NGC or PCGS. Any ideas? I know I got some good ones before, but I moved and lost all my backup from my old broadband server.
