Hi Andy ----- Looked these up in my copy of CA Chipguide (Jung/Pfaender). The $10 and $20 chips do not appear (the listed $10 is tan w/ 3 red and 3 blue inserts and the listed $20 is blue w/ 4 pink and 4 blue inserts). This would seem to indicate that your chips are fantasy chips. The $25, however, matches the description of one of the chips in the book (or at least seems to; I'm color blind, so it's hard to tell for sure: grey w/ 3 pink, 3 green and 3 red inserts). This chip is NOT described as a fantasy chip and does not even carry the notation "BELIEVED TO HAVE BEEN REMADE" (as do the $100 and $500 chips).
I do not offer this as definitive information, as I have no personal knowledge of the status of these chips. Also, do not have the Eastman CA chipguide, so don't know what it says.
THIS, HOWEVER, IS THE KIND OF DISCUSSION THAT MAKES THIS BULLETIN BOARD BOTH FUN AND MEANINGFUL. LET'S DO IT SOME MORE!!!!! ----- jim o\-S
