Found them on good old eBay and I like the $500, $5000, and $25,000 as very nice chips.

Also, the purple $25 and the Orange $500 are fantastic.

It also appears they come in two different colors as the auctions are below I found.

I don't know the seller but they are advertising for PokerChipForum.
