I would say not All the Cobb Autos I have seen have a Loop in the top of the C- this auto stops clean thats just my observation. Also his B's actually look like B's these look more on the L range
If you are buying any kind of vintage HOF autographs that aren't "authenticated" by any on the major houses, then what you are looking for is "will the auto pass PSA or JSA" if you EVER intend to sell. WIth autographs there is basically a PSA/JSA "tax" if you want to get top dollar for any autograph. So the question is really, will it "pass".

In this case I'm almost certain it won't.
