Today I picked up five sheets of Scott 1204 at face value. Looking at the sheets I noticed a difference in the inverted print on stamps on the left side of the sheet versus the remaining stamps. The yellow portion on the left row of the sheets is absent whereas not so much on the other stamps.
Looking in Scott there is no distinction between the two different types. I realize these stamps were deliberately made this way after discovery of the 1203 error. Guess I'm just flyspecking here.
