My dear best friend lost her husband to cancer a few months ago and last week she held a charity ball and fundraiser for the charity that helped during his illness.

It was a fantastic night and they managed to raise around £22,000 for the charity.
There was various different ways of raising money but near the end of the night they held an auction. Our table had many, many drinks throughout the evening and my husband was quite merry. He decided he wanted to bid on a few item but with alcohol involved he ended up going further than he should have. We got a signed painting of a footballer and signed football boots. Worn and signed by a very well known UK football player. He paid £550 in total for these.

It turns out that neither of the items actually come with an authentication certificate. Neither myself or my husband are over enthusiastic about the purchases but we are glad that the money went to charity. However when I voiced to friends that I was quite upset that there was no way to prove they were authentic and therefore had very little chance of resale, my friends stated I was an asshole for even being annoyed. She said it was for charity and that's all that matters. I still feel like if we've paid an amount of money for something thinking it was genuine we should at least get what we were promised? I know nothing can be done now but I wanted others opinions on this to see if i am being unreasonable or not.
