Wah Chang commemorative coin.
This pure niobium coin was issued by the large specialty metals refiner Wah Chang. I thought they did it just to show they could, but according to Kirk Richardson in their marketing department they did it to show what attractive coins can be made from niobium. He said "We believe niobium is marketable as a unique metal for high-end gaming tokens (niobium would be very difficult to counterfeit) and collectible commemorative." The contrast in weight between this coin and my similarly-sized titanium coin is dramatic.
They are now offering this and another commemorative coin from their website at www.hotmetalshop.com. I've got the three they have issued so far, and a new one is planned each year for several more years.
This was the 200th sample added to the Periodic Table Table.
