There is no green/yellow because the yellow label is already a qualified grade because of the signature.
The bolded part of your quote is incorrect. It was .5 because the book was incomplete. It could have other defects, that would otherwise be appropriate for a green label in a blue label submission, that would not affect the grade as much as being incomplete.
I hope that Metro makes it right for you, though.
How do you explain the purple/yellow signature series label then? I think a green/yellow label with an accurate grade would make more sense, along the lines of what they do with PLOD Signature Series books.
The explanation for Purple/Yellow is simple. It is a restored book with a verified signature on it. The label tells the type of resto and indentifies the provenance of the signature. No possibiliy for confusion.
The Yellow label already signifies that the grade is being qualified. The book is graded as though there were no signature on it. Because of the nature of what makes some of the qualified grades qualified, most notably unwitnessed signatures, a Green/Yellow label is too potentially confusing. Having to put the information necessary to explain many of the qualifiers would be impossible and it would be confusing to the consumer.
I believe the decision is correct, as it is clear from looking at your Av 4 and my Batman 181 that they are much better structurally than 0.5. Thus simply identiying the missing page provides the most information to the consumer with the least possibility of confusion. Economically it is a bad deal for folks who miss a non-story page in their page count, but as a business decision for CGC it is sound as a pound.
Well I think it sucks Sean...INFINITY
