I realize nobody's posted here in 11+ years, but here goes: I've got a Lizard Toadz decipher coin that has the tracking code scratched off except for the first two letters (PC). At the time it was given to me, the explanation was something to the effect that it was a test coin that wasn't intended for circulation...or something like that. I'm hoping to find out a little more about this coin, would appreciate any info I can get. Thanks!
