I've had these chips for quite awhile and decided to put them on my web page now. Take a look -- pictures and prices here:

I particularly recommend the "20" -- very handsome, nice large 1-3/4" size. For those who play poker, it makes for a nice card guard/card cover conversation piece. $26 post-paid-insured.
