I was really surprised at the final bids on two pieces of vintage Gibson hardware that were auctioned on eBay recently:

Gibson 1960′s original EB2D Bass Pickguard
Final Bid: US $130.27

and

VINTAGE 60′s GIBSON EBO BASS Bridge NR
Final Bid: US $179.50

I honestly expected the pickguard to go for half of what it did, and the bridge to end up in the $100 range.

Crazyness.
