Wah Chang started producing the hexagonal coins in approximately 1974-1975. These were anodized in different colors. (The round coins were just the right size for putting into vending machines.)
In approximately 1982-1984, a hexagonal coin made of vanadium was produced. You are cannot anodize vanadium, so these coins also remained the original gray metal color.
Estimated mintages are "tens of thousands".Back in 1995, I had requested a catalog and metal samples for an engineer friend of mine who worked for Genentech here in San Francisco, and the girl on the phone told me that they (TWC) had these tokens made to give to people, and they were a big hit. People just kind of liked the idea of having a cool little piece of exotic metal as a souvienir, I guess.
Basically, any individual or prospective customer who showed an interest in TWC was sent a catalog and two or three of the little medallions that you have pictured. The idea was that they were to go on a key ring. I have a purple one that is zirconium, and another that was a neutral dull metallic color, of a different metal. I can't remember what it is, but within a month or two of receiving it, it turned a rather gnarly green color, due to the high humidity here in the bay area.
Apparently, the "coins" have been (or had been) made several times, with changes to the face designs and shapes once or twice; they were made form whatever unusual "nuclear age" metals they were producing at the time. The only reason I know this is that the lady on the phone told me several times "don't test the 'coins' (medallions), we're sending 'tester chips' to you for that purpose." I didn't quite understand what 'tester chips' meant, but my friend did. The 'tester chips' were actually small 1"x2" pieces of Titanium, Zirconium and, I believe, maybe Niobium, but I'm not sure. they were designed to be dipped in corrosives to test there anti-corrosive qualities. I still have the pieces my engineer friend didn't need, along with a couple of the medallions.
I don't know of any collector value these tokens may have, but they are pretty interesting.
Know anything about this token? Please send me a note: pineconeforge(at)gmail.com
