Only 2 versions seen on the market.

1) Bought by me from the unboxer for 136 keys pure.

2) Second version has 3 owners. It's last trade was bulky, which is also confirmed as it by present owner (thanks to Beaser for responsiveness).

The first trade seems kinda sus. Hat travelled to the inventory of Littlepudintater by unknown circumstances. I tried to contact with unboxer, was added by him, greeted and I asked him about their trade, but got ignored after that.

Considering strange conversation with first owner of second version of hat and latest suspiciousness of Littlepudintater, and also bulk trade, taking 136 flat.
