Wah Chang tag, round.
This is an older, much shinier version of a zirconium tag (see previous sample for more details). According to Sheryl of the marketing department, this token was not intended for corrosion testing, but was rather just a trinket to give to people to remind them that Wah Chang supplies zirconium. She claimed that about the hexagonal one too, and she should know, but I'm not 100% convinced since the hexagonal one has a hole where you could hang it in a vat for testing purposes. This one has no hole, so it would not be suitable for testing purposes.
