I have a McGraw (No cap) as well.

Noticed my Bresnahan has some lines:

Just came across a Cobb on Ebay with two large back scratches:

I downloaded and posted pictures of it so they are saved here for posterity.

Great catch Bryan!! Two really strong scratch lines. Hopefully they will help identify some of the surrounding cards.

very cool
 

The cobb has been previously identified, but always great to see a large image preserved:

See this thread which shows the two Cobb backs:

Here's the cobb that's above the one you showed:

Three Finger Brown with a different scratch than the card on page one of this thread.

picked this one up at the show today. I am fairly new to the t206 game.

What does this mean? Does it affect value? Thanks for any help. Sorry like i said I am new to t206s

Has no affect on value. Those participating in the thread are using these backs in attempt to determine sheet layouts.

Nice pickup... Did you buy it raw, or submit to SGC on site?

Thanks for the info - pretty excited about it. i heard about the plate scratches but wasn't really sure what it meant. I hope i contributed.

bought it raw at the show. SGC was doing an on site special.

I'm pretty sure you were sitting at the SGC table when I picked up my cards. Very nice.
