Counterstamped 1823/2 Cent
I am doing a little research on a 1823/2 large cent that is counterstamped with GGG & GGGG. I bought it in a grouping of 113 large cents almost two years ago and didn't think much of it. I retrieved it this past summer and became curious and went online and immediately went to Greg Brunk's website. Then I went to EBay to investigate if there were others out there and found several pieces.
I am presenting a program on our big round browns in January at the Reno Coin Club. I have given several other talks on large cents over the past 20 years but I think this one may be the most interesting by far. does anyone have information on these and possible other resources I can use.
