If it doesn't have a certificate of authenticity from a reliable source (reputable sports memorabilia company) I'd say it's almost worthless. Could be signed, could be fake. Who knows.
I have a team-signed jersey from March of that year bought at a charity auction. I paid $900 for it, but could never bring myself to sell it.....just sayin'. And I wear it often, especially here in BC ha ha.
