this looks like the one you told us about in the other thread - special edition for Sweden.
There are a few on here who would like this bottle, myself included. Many would like to drink it, others to keep it as an investment.
But as to the value?
You have only just bought this, the value is what you paid for it or what you can sell it for. I would say there is no other precedent just yet.
You could always offer it for auction on any of the auction sites, the value will then be what you get for it.
