Michael,

It looks like all, except one (row 3, chip 5, using the first scan), are cancelled (over-struck) with a starburst-like hot-stamp. It looks like all but 2 are are RTPlastics (Gamblers General Store) chips. For the two that are not, one is the dragon mold (row 3, chip 3) and the other is a dice mold (row 3, chip 5, again).

Some appear to be casino branded, especially the chip in row 5, number 6; the recently posted here on TCB and discussed Golden Gate 500 NCV. I am not sure about values for any of these, but the frame can certainly be re-used!
