Whenever I see something that looks like it *might* be a revenue use, my curiosity is piqued, even if we can never truly know the answer.
This irregular block of 11 of Scott #112, the 1-cent Ben Franklin of 1869 has some condition issues, but the sprawling "Nashua N.H. Mar. 4, 1870" manuscript cancel in magenta is quite interesting to me.
This block was sold by Matthew Bennett International in 2008, where it garnered $826 including buyer's premium. It recently resurfaced in a Paradise Valley auction, where I acquired it for less than half that amount all in.
Was this from a parcel front, an oversized cover, or perhaps an improper revenue use? The cancel method is more indicative of the last of the 3 than a postal use. The extra 11th stamp at bottom right conveniently completing the date also leans towards a revenue cancel rather than postal, in my opinion.
In fact it reminds me of the all-over manuscript cancel on a similar improper revenue use of a large multiple that I have (also shown below).
So how do you think this block was used? Unlike the other example shown, there is no document or document residue on the back to provide any context as to its use.
