HOF Autograph questions?

[Lordstan]

Bam,
Welcome to Net54. You may recognize me from SCN (same username).
The crowd is is a bit more advanced than the group over there. Many here are also over there. I think Kevin's answer is pretty much perfect.
The only thing I have to add is that most, but not all, collectors here are lukewarm, at best, on the TPAs. We talk freely about the good and the bad. My opinion on them is pretty consistent
1) Having a cert doesn't mean I'll accept it's real above the opinion of the group here.
2) Having a Cert/Slab doesn't change what I will pay for a sig.
3) I won't send something in for a cert until I am about to sell it and only if I think the cert will increase my selling price dramatically. Remember, all the TPAs are one big scandal away from becoming GAI, so spending my money beforehand makes me concerned that could be wasted.
