That is a little expensive, but it would go well with other real chips for $1 and $5.
Even though this one is white, I really like it (mentioned
over here):
Other than that, I'd really like to get either of these (although could get a bit expensive for some $5 chips, not sure how many I'd want to get for a 25c/50c game with 8 players):
These are also nice looking:
A hotstamped ASM for a 25˘ chip sounds like a decent alternative, though. Much cheaper.
