I have 10 consecutive UNC $10 birds that I was going through and noticed the the ink from the front of one note transferred to the back of the next note. From a distance it just looks like light ink smears but when taking a closer look you can see certain aspects of the note that were transferred. ie the 10, certain portions of lines etc. There are only two notes like this, but only one is defined.
Is there a specific error in the catalogue that this would be part of.....It isn't a heavy ink smear just more of a transfer of wet ink ??
