During this period, ten other offices interested in the prepayment process issue provisional stamps. They are spread across nine different states and sometimes serve very small communities, for example Lockport NY which was not yet incorporated as a city at that time.
The solutions practiced by these offices are original and varied. Millbury, a small city near Worcester, Massachusetts, issues a stamp whose characteristics mimic the model from New York.
The Millbury postage stamp exists only in 5 cents with the portrait of Washington, like the New York stamp. Its back is gum plated. Its manufacture is however home made. The portrait is rough, and the stamp is woodcut printed per unit in black ink on a bluish paper.
The production of the Millbury stamp is relatively abundant compared to some other small offices. 18 copies survived, including 8 on envelopes sent from Millbury from August 21, 1846 to January 12, 1847.
The envelope of January 12 has remained in great freshness with a stamp in superb condition. The stamp has been cancelled like a modern stamp, with a red ink marked 'PAID' that overlaps its edge.
The Millbury stamp was a local prepayment facility and not a payment guarantee for the receiving office. This guarantee was provided by the date hand-stamp with the identification of the office of departure, here Milbury Ma. This fantasy spelling with a single 'l' has lost a plausible explanation. A large numeral 5 in a circle confirms the paid price.
This envelope was sold for $ 460K including premium by Siegel on March 28, 2012. It is estimated $ 300K for sale by Robert A. Siegel in New York on October 3, lot 6. Here is the link to the section dedicated to the sale of the Gross collection on the website of the auction house.
