Gene,
Probably made by someone, for the indians, who had blanks (just like Gamblers Bookstore has for sale now) and stamped them out. Gene, there are many blanks for most molds available. However, "THEY" whoever they are - cannot reproduce the type of gold foil to match the period. Also B.C. Wills added something to the clay of these blanks - they kinda look like plastic. Just my opinion and others who I have discussed this problem with. Best, Jim
