A number of persons have offered monos on eBay and elsewhere saying they were roulettes at a named club. No way to tell other than to take the word of the seller. In 1996 I attended a sale of casino items including tens of thousands of gaming chips from PJSullivan's old Saratoga, NY casino. The only thing my "friends" would allow me to successfully bid on were four boxes of roulette chips which were mono "D" and "J." If anyone needs these whether they accept my attribution or not, let me know.
