El Salvador 1894 1c on 11c Vermilion Double Surcharge Error Multiple Used. Scott 104b
Block of eighteen stamps showing the double 1c surcharge error, currently unpriced in Scott. The block contains the 'dropped n in Centavo' variety, only found in position 27 on the sheet (middle row, second from right). The block is MNH, inferring CTO with a mute violet star in circle cancel. A scarce item.
