in the poker chip world, i've learned that those "11.5g composite clay, with metal inserts" chips that everyone gets are pretty crappy.
i'm guessing you don't want high-end clay or ceramic chips which would cost around $1 per chip.
if you're looking for large quantity, and most bang for your buck, check out these "faux clay" chips:

they have no metal insert, so they sound nearly identical to casino clay chips when thrown around. they also stack really well, which is a sign of a good chip. best of all, the price is very, very nice at $0.045 per chip. these chips have a real strong following among die-hard, nutty poker chip folks:

i say, buy the Faux Clay chips, save some money and spend more money on booze
