Anniversary (#BluePi) Valuation?

[notrodash]

So I managed to get my hands on a blue anniversary edition Raspi Model B last year, but I don't have any use for it because I already have a standard one. It's still in brand new condition.
Since it is a special edition item, I assume I can get a bit more money for it than just the standard model.
Does anyone know how much these go for? I'm having trouble finding past auctions on ebay.




Note that I'm probably not going to sell it any time soon, I just want to know roughly how much it's worth.
Thanks!

Starting price would be about £20 and then let eBay buyers decide how much they'd want to push it to.
