Do sellers really not know when it's a facsimile signed ball?

[drcy]

When you sell something it is implied that you are saying it is authentic as to how you describe it. Offering a "Babe Ruth signed baseball" then saying "I never said it was an authentic signature," or offering a "diamond ring" then saying "I didn't say it was a real diamond" doesn't work. That's would be as legitimate a legal defense as saying you can't be held liable for the deceptive description because you had your fingers crossed behind you back when you composed it. He says signed and signatures, end of story. A stamp isn't a signature, and stamped isn't signed.
