I'd like to know what you all think are the hardest steels/irons to aquire. These may not necessarily be the most valuable. I'll start off with a couple I haven't even seen for sale.

Terminator 2 Japan Version 2 Black

I also sold Iron Man FS, Iron Man MM, Clone Wars NL, Indiana Jones, and some other hard to find SteelBooks. I temporarily had thrown in the towel, and now I miss those rare SteelBooks. Oh well, life goes on
BTW, luckily I still have IB FS, and other rare Steelies
