If you submit something and it fails do they put "Fail" DNA on it so the next time it comes in they just look for the DNA and fail it again?

If you ever get a chance to get his signature again I would highly suggest taking a smartphone and video him signing. There's almost no way to argue with that if you can see him, where he is signing and the finished product.

I will throw this one thought in. Back in the day I was one of the few people who would authenticate McGwire signatures. There were a few occasions where I would get a signature that was just signed badly. Meaning maybe it was rushed, or bumped or something out of the "ordinary". I made a decision to not authenticate items like that. I returned the money and told the person I thought it was probably good but I'd rather not have to explain why something was good when it didn't match up with the "usual" type signature.
