I picked this up at an auction held at my alma mater. General Motors donated this and there weren't many other soccer fans, so it ended up in my hands. It is pretty cool to have a shirt from my favorite team and from a match vs. Real Madrid, but I am going to sell it. I don't have any idea how much something like this is worth. I have seen some ManU shirts sell for anywhere from $800-$3500 plus, so I put it on ebay for $3000 obo. Any guidance on value is appreciated.
