Doug--I agree with your views on variations, including the 58 Herrer and the 57 Bakep---and the 3d 59 Spahn and Haywood Sullivan ( even though I paid $ for all of them just because they are in the SCD Catalog). Another recurring but rare print defect in that set is the Ramos card. There has been a high grade version of it on ebay for some time with no takers. But that defect is not isolated. I have seen others on ebay and have one myself. But unless it gets listed, only extremists like me who have the sets done and are looking to expand them are likely to pay any premium for them.
All that power Bob L.....
