I appreciate it! I just weighed the tokens in each set and came up with 17.4 ounces and 17.6 ounces. This is "regular", not troy, ounces. I also carefully examined the edges of about a dozen tokens and could not find any markings (many have reeded edges). The only marking I could find on the obverse or reverse side of each token was the Franklin Mint "F". Sterling silver or .999 fine silver? Nobody seems to know for sure, based upon the emails I have received. I guess I'm not too surprised that Franklin Mint silver stuff isn't worth much more than scrap value. Looks like my sets are now worth less than I was thinking earlier today. I'm surprised at the lack of information about these sets on the internet. They are still for sale.
