Who is Alex Krycek in X-Files and is he popular?

[satyrnfive]

Got an autograph card of him in a pack of cards from 2005. Wondering if it's worth selling. I figure if he's popular in the X-Files fandom it might be worth doing it. Anybody know? Or anybody want it?

It's from Inkworks X-Files Connections Autograph A-6 (nicholas lea as alex krycek)
