they are, believe it or not, much tufer than the 30's......I search all the time....true many go unnoticed, but they are id say, 4 x tufer than the 30's....
I have contacted sgc informally and expressed a great need for noting the factory #'s on the flip, or more info...
this would help GREATLY in tracking front/back combo scarcity's...
TPS's could make more MOOLA because, I'm sure, collectors would prob re sub cards for additional info on flip such as a factory designation...Vin Moretti and I were just talking about this the other night....
btw
I have the recently confirmed JOE LAKE OM BACK
where the scrap at??
