A US 1851 1c blue Franklin stamp will auction at Daniel F Kelleher Auctions in New York on December 1.
The stamp was introduced following a drop in the cost of postal rates in 1851.
The cost of delivery anywhere in the US, regardless of distance, was changed to 1c. Although pre-payment was optional, collection costs were increased.
This was a powerful incentive for most people to switch to pre-payment, which became mandatory in 1855.
This stamp is graded VF-80, placing it among the very best of the 90 survivors. Only two are graded higher.
It's expected to make $100,000-150,000.
A US 1923 2c Harding is another highlight, with an estimate of $35,000-50,000.
The stamp was only sold for a short period following President Warren Harding's death and was phenomenally popular.
Harding was a well-liked leader and millions turned out to watch his funeral train pass by.
Well over a billion of these stamps were printed, in three different variants.
This is the rare #613 version, of which only around 50 remain. This example displays a very light cancellation and is graded "fine".
Other highlights include a US 1918 $2 orange, red and black, which is valued at $20,000-30,000.
