You published a medal from the Stacks Americana auction ("Some Stacks-Bowers January 2012 Americana Sale Lots) in the 1-22-12 issue which matched a similar medal in the research box on my desk, one that I purchased at the ANA in Chicago last August.

My example is silver, 40mm diameter but only 41.3 grams in weight; other than the composition and the attached loop, it is identical to the gold specimen in the sale. Of course the actual specs on my silver medal don't match the weight noted on the gold piece. Any further information on the medal or Mr. Wiss would be appreciated.
