~~~ incuse graphics.

Perhaps if you search the early works of those who professionally write gambling chip auctions you will see actual photos of those chips... and perhaps further study of those incuse graphics will lead you to additional information.

Otherwise, the "FLORIDA PALM SEAL AND CREST CHECK" (catalog # 30F234; H.C. Evans-page 24 in their catalog -- and that full page seen on page B-10 in Harvey's Guide to Collecting Gaming Checks and Chips, by Howwdy Herz) was a running stock item with distributor H.C. EVANS, who offered them to anyone who was willing to pay $7.25 per 100 units.

Furthermore; most responses to posts such as yours accurately quote authors' work/catalogs/pricelists... with hardly ever a shot-in-the-dark guess as to for whom a USPC chip/check was made for. Such posts (responses) also include information as to where such chips have been reported to been used...

It might also be a good idea to respond to a post you've made and not start another thread as a follow-up; especially where there have been responses.
