E90-1 "shaded" back variations?

The bigger error that the grading companies continue to perpetuate is their need to designate blank cards such as these as coming from a particular issue, when, because of shared poses between different sets, they can not be accurately pinned down. The vast majority of M101-4 and M101-5, and their associated sets that share designs and photos, as well as the M135 and associated sets are also examples of this (recently saw 'Boston Store' blank backs--how can they know?) haphazard designation by the grading companies.

I agree Brian. There is no way the TPG's can know which series many blank backed cards came from. The way I classify them, and a way that is at least standard, is to go to the least common denominator of ACC numbers. In other words if there is a blank backed T206 then I would use it instead of a series with a higher number, same thing on the E cards. If an E card has a blank back, and the front was in the E90-1 series, then that is what I use. It's at least a consistent system and one I would propose to always be used, again, for consistency. regards

ps...with regards to the original question I don't think these shading errors should be documented as true errors but as small print defects....or differences
