For what it is worth, in 1998 I bought some James Bond chips from Paulson to put on eBay to counter the rip-off auctions. Anyway two points:
(1) Paulson in 1998 was selling all six denominations, and the $100 came in both cog and round inlays, and the $500 came in both six-sided and round inlays. (I'd sell any of these (except the 6-sided ones) for $2 each, plus $1.50 for postage/insurance. You could also get them for 65 cents (?) each at the Paulson store.) (If you know of any other inlay variations, please let me know.)

(2) It is almost amusing the way the Paulson people tell such changing and disjointed stories about the chips (origin, in movie or not, history of the inlays, etc.).
