I posted this in the rare badge post but thought I would post it here as well. Very few of these are known, probably less that 10. I've seen 2 on epay, a mutilated one made into a brooch (also on epay) and one in a display at the last MCC of C convention in St. Catharines. It was fluke buy on my part
but I pretty happy that I was there at the right time.
Enjoy,
Greg
