A no roulette, imperf, or imroulette pair of the one cent documentary. Rare to the point of having an italicized value in the 2008 Scott catalogue, unlike the part roulettes, the true imperf is quite scarce and merits a reasonably high valuation.
I acquired this pair and the accompanying certificate from the Henry Tolman sale. Its pedigree can be established prior to Mr. Tolman, as the pair was sold in the Morton Dean Joyce Sale nearly 15 years earlier. Mr. Joyce put together the single greatest collection of US revenues.
