This morning I am opening up a new web site to explore the die varieties, counterstamped inventory and types, grades, and other items of interest. http://www.stonemountainhalf.com We have already expanded the previous counterstamped coin census from 140 coins to 285 and believe with a little help we can go much further. http://www.stonemountainhalf.com/counterstampcensus.html Our inventory starts with 48 coins spanning 16 different grades. No one has ever completed a grading set for this series and that is one of our short term goals. We have another 50+ coins in the pipeline and hope to be at 100+ coins by year end. For all 48 coins there is a dedicated page with PCGS high res images and a discussion of that coin's features. http://www.stonemountainhalf.com/21025455_66.html for example This is purely a non-commercial educational effort and we hope you enjoy. As we have other updates we will post new information here. Thanks and enjoy.
