The 20c Error of Color was originally considered color trials or proofs when they were first reported back in the late 19th century. Although, they are now considered with certainty to have been printed at the same time as the other values of this issue, invalidating that theory of these errors as proofs. Goodman states "rare in pairs or blocks".
Each stamp with expert's handstamp. Scott value $7,000.00 as singles with no premium for positional block
