They originally sold for $99/500, in a nice, solid black case. The initial design for these brass chips was the "BINYONS [sic] WSOP HORSESHOE 2005 " version, until the Horseshoe's legal people put a stop to that.
All I know for sure is that when I bought the Binyons chips through a 5stardeal-type eBay seller on Long Island, they were the only version of these brass chips available on eBay. Then about a year later, when I wanted to add on, more $1s, the Binyons had been shut down, but I was able to find the Tangiers chips on eBay.
They were my gateway from dice chips to chip hell.
I still have the Binyons (for sentimental value?), but I dumped all the Tangiers when we moved to FL.
I used to have a set of the Tangiers. I think I paid 39c / chip for them. They were actually kind of cool. When I put them in play, alot of people said they were their favorites, although I wouldn't go that far.
I think I got 25c / chip when I sold them.
I never saw the WSOP version but there was another 'Centenniels' chip that was just like them. I think they were around 30c chip at Spinettis.
