I don't know where you can get more, but I remember about a year ago someone put up "all of them" for sale on eBay. $10,000 for 10,000 chips. $5s, $25s, and I don't remember what else. No one bid on the auction and it went unsold. Now I see the $5 chips one at a time on eBay, but I don't know if it's the same seller. Good luck, I'm curious to see if there's another source too.
