Lot 1178, 1890 Great Britain one pound brown violet Victoria with rare THROGMORTON AVENUE squared circle

We recommence the auction today with more postal history. The Commonwealth section features many lots of Great Britain squared circles.

Lot 1178 THROGMORTON AVENUE F / E.C. a fine and centered strike P / AU 16 / 90 on a £1 brown violet Queen Victoria stamp (tiny tear at right). When the Handbook was published, only two strikes of this office were known, one (offered elsewhere in this collection) on a £1 stamp and one on a 1sh stamp. This is a third, unrecorded example. A rare squared circle, with a rarity factor of 475. The stamp alone catalogues $4,500 in Scott, including 50% premiums for very fine centering and clear c.d.s. postmark – squared circle postmarks are quite a lot rarer on this stamp. S.G. #185,cat £2,800. Estimate $500.
