Among NJ Copper collectors there exist photographic plates that we call Nagy Plates. These are credited to the same Stephen Nagy that John Lupia posted the biography for in the last issue of The E-Sylum. Other than these plates, I don't know of anything else he had done for colonial numismatics.

I'm flying to Harrisburg PA on Tues-Sun for the biannual national APIC (American Political Items Collectors) convention which is 100x more rewarding and interesting than many other shows...with bourse tables less than 10% of what they cost at the ANA and considerable room hopping activity before the bourse.

You'll see and can buy more small historical collectibles than you ever imagined existed for a tiny fraction of what you'd pay for an equally rare coin or currency item. This field was popular amongst numismatists back to the 1860's, according to early coin auction catalogues. Sadly, more and more of this stuff is being slabbed now by numismatic dealers seeking to expand their offerings and engage collectors priced out of the rare coin market.
