I understand from archived threads, that these are rare items.

They are rare but not worth 15K. I can't imagine someone paying  such an elevated price.

I agree and also, have to wonder what's prompted the seller to ask that amount, without saying anything about it's rarity.

£11K! Gotta be some kind of money laundering thing I should think.
