I just received these 7 chips (numbered 1 to 7 here) from a friend in the Netherlands. Both sides shown below. I own just these 7 (might get more). There doesn't seem to be any listed in Chip Guide ( http://www.themogh.org/cg_chip2.php?id=N3XXH1&s= ). Please make offers, I might wait a few days, then decide what to do -- I have no idea the value here. According to the Chip Guide, the Holland Casino group owns 13 casinos; it looks like all are in Holland.

A few notes:
¶ #1 and #2 have good hot stamp imprints on only one side. Other side, worn. (The other chips are in very fine condition.)
¶ #6 (American Roulette Championship 1998) says "Amerikaanse Roulette" on the reverse (side with blue background).
¶ #7 (the 5 Euro Jetton) has a picture of a horse on the reverse side and the words "Holland Casino Enschede 27 Juni 2002" ( side with blue background). Enschede is a Dutch town near Germany.
