Is that Boomtown colored coin a doubloon? I was told in the casino's early years they had a float in the Biloxi Mardi Gras Parade and also was used in other parades along the Mississippi Gulf Coast. I have been looking for one for some time.
Also, the Pride Of Mississippi token...is it attached to a clay chip? Very nice finds. If this guy has other chips available, I am sure Mississippi collectors would be interested.
