This question is useless without the context as there is surely one.
Did the OP win a pile of junk at auction?
One person's junk is another's treasure.
Why does the context of the question have to be questioned. A pile of junk, won at an auction, would be worth What I'd paid for it. Reason being, that is what I felt it was worth, whatever the amount. And I do go to quite a few auctions.
However for those that want a fuller story , for them to comment on, read on.
Item in question is/was a printhead, won on
ebay. I have given the cost, to myself, as the value of the item. Others are saying its worth more. I paid what I thought it was worth. Seen during the week at just under £100. I paid a lot less than that.
This doesn't sit well when it comes to official form filling, as I'm finding out. "It must be worth more than what I paid, so please enter the actual value of the item."
As far as what the PO will accept as proof of value, they won't accept a shop receipt as proof.
