Panama, N.Y. Jul 21 [1850], handstamp used by U.S. Despatch Agent in Panama (New Grenada), excellent strike of black cds with black New York "Steamship 30 cts" handstamp on 1850 folded letter addressed to Philadelphia, datelined "Panama July 14th, 1850" and reads, in part, "…In great haste I sit down to give you a few lines previous to my embarcation tomorrow for San Francisco. I have now been here nearly a month & as the place bears every appearance of a down hill progress before long, I thought I would not risk my fortunes, with those of Panama…I shall take measures to have the letters which I wrote for in my last forwarded to me from Callao & shall probably make use of them at some future time. Please write immediately on reciept of this to Sacramento City as heretofore…I have shipped on the Columbus, for San Francisco & have to go aboard tonight…tell me what are the prospects of Realejo becoming the western terminus of the Nicaragua route to California & whether that route bids fair to be the route in future between the U. States & California…Isaac Wister", Extremely Fine and choice, Very rare handstamps; with 1978 P.F. certificate.Estimate $1,000 - 1,500.
ONLY ABOUT A DOZEN EXAMPLES OF THIS ERROR ARE KNOWN, WITH THIS BEING PERHAPS THE FINEST.
This datestamp was intended to read "N.G." for New Granada, but was mistakenly inscribed as "N.Y." The marking was used exclusively on mail originating in Panama or delivered to the Consul there. Both the New York "Steamship 30" rate marking and the "Panama, N.Y." U.S. despatch agent's markings are only known used for a few months in mid-1850.
