Forgive me if this has been discussed, but I'm relatively new to the forum. I found an autograph listed on eBay. After doing some research, I found the exact same item on Hollywoodmemorabilia.com. It is the exact same item, with the same Psa/Dna number. Is this strange? Or does this somehow make sense that the same item would be listed in two different places...for slightly different prices too.
