Hi and Happy New Year! Submitted for your approval is an image of my Scott US #700 Bison (perf. 11x10.5) and one from an internet ad for the same stamp with a PSAG Cert, graded 98 (the one that says 1/2 in the top right). They look so different. The engraving detail of my stamp looks much more intense (see the thin horizontal lines in the sky and on the ground. The second major difference is the large, tapering white area from the bison's head through shoulders all the way to the left. What's going on here? Scotts has a sublisting for #700, "Retouched in head (20552 UL 83)", worth about twice as much as a normal mint stamp, with no image to identify the stamp with. A Google search did not elicit any pertinent documents or images. (And that in itself amazes me!) Can any of you explain the differences in these stamps? Do you think my stamp is the "Retouched in head" variety?
Thanks, Dave Schwartz
