I just acquired some of these scarce Defiance chips (coded PWNR on page 320 --Wheel and Faro inlaid chips). They are not in the first edition of the book, and I never came across them at flea markets, etc.

They are made to look like a fort. See: http://en.wikipedia.org/wiki/Fort_Defiance

I had only four 7-color sets. Very fine condition. Just got them. $30 plus $3 for postage? PayPal OK. Return privileges. ( I sold 2 sets on this Board, have one set on eBay now, and this one set offered here.)
