Centris Black LE

I received this geocoin from Centris during a large Groundspeak Forum "math trade" where people put in what they had to trade, then they selected what they would take in return from the large list (with a few complications, I recall), then a program figured out who was sending what geocoin to who. I was extremely pleased to discover I had scored a pair of Centris' highly prized trade-only geocoins, including this limited edition version.
