APC error label update
Back in January, we mentioned the existence of Automated Postal Center error labels that featured designs incorrectly printed on paper that already bore preprinted designs. These error labels looked like they had been accidentally overprinted.
John Ryskamp, a contributor to U.S. Stamp News, recently wrote to let us know that there are by his count 83 different error varieties. You have to count each possible printed rate (forever, first class large envelope, priority, etc.) to reach this total, and the glossy blocks that appear over the preprinted mailbox image can apparently be found with both square and rounded corners.
While APC labels are somewhat outside the mainstream, there’s certainly opportunity for specialization, and the “wrong paper” errors, as Mr. Ryskamp calls them, provide some interesting variety.
