Good job, pyrbob!
You really are becoming an expert in a very specialized topic.
I am wondering what you plan on doing with all of your information?
I know there are references to an old booklet but I think as it is old and out of print you might be ready to supplement it?
You could publish another booklet or maybe have an in-depth webpage.
Some ideas to include:
History
High resolution photographs, Die Markers
Accurate weights
XRF Analysis
There was also a member that posted about detecting them by magnetic means.
I also am interested in where this lot of coins came from.
Do you think they stayed near his base of operations, or spread throughout the country?
I
previously posted one I acquired in Georgia.
Best wishes,
