I just got a bottle of Nic-A-Date from a member of my forum, and this is good stuff. I had 2 Buffalo Nickels, one of which was an S that was completely dateless, the other had a barely recognizable 20. A couple drops of the Nic-A-Date, and this is what I got... Before... After... Before... After... Just don't try it on silver or copper... BAD, BAD, BAD!!!
