Siegel’s 1 October 2026 Ryterband sale offered 355 lots in two specialized collections: vending and affixing machine perforations, followed by modern errors. Linn’s reported a block of eight 1908 five-cent Lincoln stamps with Schermack Type III perforations as a leading item.

The block, identified under, was described in the auction material as the largest recorded multiple of that variety. Other highlighted lots included experimental perforations on a Lincoln pair, a CIA Invert and an imperforate-between Tom Sawyer pair. These are descriptions of the completed sale’s offering, with no prices realized established here.
