My sister-in-law gave me some items that were my brother's.  One thing that I really like and will keep and have framed for myself if it is real, is this Deion Sanders Cowboys official authentic jersey that is signed on the back.  I have attached a few pictures of it.  She can't find a COA for it, so I'll send it to JSa or PSA if it looks like it could be legit.  Just don't want to waste the money it is completely off. 

Thanks again in advance for your help.
