Chris,
Check out Mike Spinettis web site. Next month he will be offering a metal core chip set for about $0.80 per chip, plus or minus, in lots of 25. They come in $1, $5, $10, $25, $100, $500. You can also see images of chips on ebay where he is selling demos for about $10 per set. Chips are from imaginary "Tangiers Casino", in Las Vegas. Nice looking chips.
