Blood’s 15L18 and US 1857 on Lady’s Envelope, Nov. 22, 1858

Red Blood's double-circle datestamp ties 15L18 and is struck again on small envelope bearing 3c 26 tied by black circular grid with Nov 22, 1858 Philadelphia large octagonal datestamp. Address has been erased.

A census of covers known with the red Blood's handstamp was published by Marc Stromberg in The Penny Post for October 2018. This cancellation is quite scarce with only 14 reported (this cover was not known to him).

There are only two covers “to the mails” with 15L18 and US postage, this one and number one in his census.

Scott value of $350 is for the usual black datestamp, and does not account for the scarcity of the red cancellation, in use only from Nov. 22-26, 1858.
