I think the source of what Bill has heard is the link. And as far as I know,there are cropping differences on each same pose green tint. Darren is the expert on that. I think it has been reported that PSA has been reluctant to to note the green tints on slabs because if you are looking at just one card at a time they can be hard to differentiate at times. I think that is true . If they had Darren's comparison scans, it would be easy. Bartsch has reported in SCD recently that they will be running an article on the green tints, maybe that will help. Hope Darren has had some input on it.
