It is a sellers market when it comes to first edition metal TREZOR's. I can price it at whatever price that I feel comfortable with. If I want to depart with this magnificent piece of BTC history for $500, so be it. Who are you to say what it's worth is?
Nobody said that you can't price at it what you want, however that does not affect its value. You can try to sell it at $10k if you like, but that won't change the fact that it is worth X. This is why I wanted to see other auctions, in order to see whether this price can be justified. In order to not clutter up your thread further, please PM me if you have any information about other past sales/current ones.
Good luck with your auction.
