[QUOTE="gsimonel, post: 2971196, member: 82549"]You can remove the patina from the raised area using a little dish-washing soap and a green, Scotch scouring pad. (Off brands generally don't work.) In my opinion, this makes the coin even less attractive, but it will make it easier to identify. Nowadays, however, if I have a coin with a really terrible patina, I use electrolysis to remove the entire patina. Over time (read: many years) the coin will slowly repatinate on its own. (I detest artificial patinas.) The problem it that you never know what's under the patina. Sometime you reveal a gorgeous coin with a lot more detail, sometimes you reveal an ugly, pockmarked mess, and generally you can't be sure in advance which you'll get. So maybe start with the scouring pad, and if you don't like the look of what you find up with, then go to electrolysis.[/QUOTE]
