I am currently running an auction for it:
Puerto Rico,old,scarce:Flamboyan, San Juan, casino chip
Item number: 150440235466
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150440235466

(1) I listed it here: Collectibles > Casino > Chips > Individual Casino Chips > Other [8137 auctions now in that category ("Other")]
That is where I run virtually all of my chip auctions. It is an old category, and it is the largest chip category, largest in the number of auctions.

(2) But do you think it would do better here? Or list it here as well as in (1) above.
Collectibles > Casino > Chips > Individual Casino Chips > $1 [4884 auctions now in that category ("$1")]
