I bought a few individual $5 chips from Spinetti's (eBay) and some other $5 and $25 from other eBay sellers. I did not buy any of the "Mint Uncirculated" chips from one seller, all mine were "table played."
All the chips I bought had been professionally cleaned, so they were not at all dirty. In fact, they were too clean for my taste... I like a little character. I had to oil them a couple of times before the oil soaked in and they felt right to me.
Mine appear to be well-used, in that most of the edges are pretty rounded, but the molds are still reasonably sharp. They shuffle well and stack OK.
One note -- they are a little thinner than most other chips. I don't know if this is from wear and/or cleaning, or whatever. I can fit 21 Dunes in a regular Paulson 20 rack.
I bought mine to collect, and don't have a large enough set for playing. I would certainly use them for a playing set, but I did not want to spend that much cash.
Here are some pictures of the faces and edges of a few representative sample chips. Chip #4 will stand on edge, but that's the exception... most are too rounded. But don't get me wrong, I really like these chips!
