Holy Toledo, $5200 for the IC badge!?!
I put it on my watch list just to see where it would go. Apparently the answer is, through the ceiling, past the roof, and up into the stratosphere. Is that some kind of record for a pin that wasn't a founder's? It's hard to believe anyone could expect to resell it for more than that, so at least I think Pi Phis can have confidence that if a collector bought it, that collector apparently values it very highly and will treasure it and take very good care of it.
