Since I've had my account since mid-2007, it's really interesting seeing all of my old hats and how few of them are still on sale. One of my first hats is from the 2007 paintball tournament, the T-Bone Visor and there were only 168 of them sold. And I have one. :o
Also the classic Fedora bottom price is R$24,500. Holy. stuff.
Even Clockwork's Headphones, which were expensive anyway, R$28,499.
The Void Star which sold for 20,000 tickets is now R$35,000 and just under 2000 exist.
A Hockey Mask which apparently only 18 were sold I have. I think these were awarded somehow.
