Only 6 copies on site, given exclusively to the members of the winning band during the battle of the bands event a couple years ago.

I was part of the winning band.

I'm not sure I want to sell, but I legit never use this item (I use the 'public' gold version instead) so I'm curious of its possible worth

If they keep it exclusive to 6 copies, I would say 1.5-2.5billion. It might be hard to find a buyer, but I know I wouldn't sell for anything less than that.

However, the elegant skull ribbon which was previously a 10 of a kind contest prize was unceremoniously dumped in the MC for 50mil.

As a buyer, I would risk 500mil on the threat of a massive rerelease.

Thank you for the insight! I sure hope they won't rerelease this unique item, since it was made for a specific group of people, but we never know with Subeta

A buyer manifested themselves, so I ended up selling it for 2 billions, which seems fair considering the current item status
