When this button/commemorative Phish pin (no backing) was tested with an XRF instrument it was negative for lead, cadmium, mercury and arsenic. For those curious about what kind of metals are in something like this, here’s the full XRF summary for this item. I have never tested a modern pin/button like this that was positive for lead, mercury, cadmium or arsenic… so in general they seem like a good choice (in terms of a category of things to collect!)
Correction: I have been told this is a “stash tin top” – although I don’t ever recall seeing the bottom! Lol!
- Tin (Sn): 31,700 +/- 400
- Zinc (Zn): 642 +/- 172

- Titaninum (Ti): 170,500 +/- 2,800
- Cobalt (Co): 20,100 +/- 1,700
As always, please let me know if you have any questions.
