great question......as you know, brown old mills are printer's scrap......scraps are unique unto themselves..

..
cobb backs shouldn't even be included in T206...
broadleaf 460 should be the "rarest" possible, issued back....
cobb, brown old mill, upside down backs, blank backs are in there "own catagories" imho.....
brown om pricing can go anywhere
I'm guessing a fair price should be 10-15 k.....but putting them up in price range next to design change proofs, planks, ect???? just seems a little much.....I'm jealous tho since I don't own one of these beautiful scraps
