This is a scan of a very unusual chip sent by Doug Smith that I thought you might like to see. The following notes are from Robert Eisenstadt:

" ¶ great chip. Very rare and unusual. Not in the book. These chips are 1-7/16th inch diameter. When you see one, you will see that it is and looks much smaller than the ordinary 1-9/16th inch casino size chips! Apparently these were experimental chips that never took hold. I know of no other chips this size made by any gambling supply house."

Thanks Matt & Doug... and thank you too Robert!
