Not much value (none of my stamps really are), but I put these stamps side-by-side and see a noticeable color difference. Scott 55 (SG 62) is described as "purple-brown/straw" in the SG book. (Violet-Brown/straw in Scott's). Do you see a difference in these?

In addition, I see a few scratches that almost look like sun-rays near the mountains on the top stamp. These don't appear on any of my other copies. Is this an unlucky plate scratch?
