fake-auto experts?

[cmixer]

i bought a small lot of signed cards on eBAY -
he said "in-person" autos, at signings ...
but never provided true COA's or proof.

Can you confirm any of these autos?
(or disprove them?)
I imagine they are all good, or they are all fake.
Just wondering if anyone has some handwriting opinions ...

my 2 cents, they all look like the same marker
