Precancels

Precancelled panes are from booklets intended for non-postal purposes, with the stamps cancelled to prevent any possible postal use. These booklets were used for trials, as samples, as reference copies, and with the introduction of commercial advertising in edition (5), for advertisers voucher copies.

Cancels were applied in pen and ink, with circular obliterators, with SPECIMEN and CANCELLED overprints, and with punched holes.

Obliterator identification numbers (OIDs) are included in many circular precancels, usually at the bottom of the ring and occasionally in the centre. A list of those seen is given below each type, but there are likely more.

Some precancelled booklets are punched, usually in the top left corner, others are spiked.
