I searched, but didn't find any discussions about challenge coins on the Forum. Has Spyderco ever released a challenge coin?
I think these would be a very popular item. Especially with the company's focus on Tactical Ops - challenge coins could serve as a great advertising tool. They can be relatively inexpensive to design/manufacture these days - and Spyderco could sell them for $10-$15 each through SFO.
Sal, is this something you and your team have talked about?
