Picked up an assortment of gear the other night from a guy in a bar (don't ask me why he had a full rack of gear splayed out at a bar, I couldn't tell ya), and I'm curious when these Exentrics were made. I can't find much info online, and I've never seen the anodized finish on hexes. Anyone have an idea? Do these have any monetary value beyond 10 bucks/hex as would be more standard on the buy/sell forum? Thanks
