Eric,

There are large and small sets of chips from closed casinos that come up on Ebay all the time. There was just a large set of chips from the Vineyard Casino on Ebay last week that sold for around $2.00 per chip. Here's the link:

Keep an eye on Ebay...Im sure you'll find a nice set.

Another option, is to put together a set by trading and or working deals with low value chips. There are some collectors that have put together large sets of chips from Puerto Rico.

Good Luck.
