My notes indicate only 3 or 4 Dixie Ducks (dollar value) were ever found, the boat operator may have destroyed them all. A limited quantity of higher denomination chips did appear a year or two ago. The Duck then used "Coastal Gaming" chips which appear also to be quite rare.

I have a $1 Gator Games notched sample chip, pink in color (mistake or variant) but it's not for sale as I wish to keep a set of all denominations. Don't know if those were ever put into general circulation, my understanding being that the "cardroom" (more of an entertainment arcade) was not allowed to open as such.

Know nothing about the other chips you post but keep lookin' . . . perhaps some day you will encounter one (hopefully more). Anything's possible with this hobby!
