David Feldman, Geneva, Dec 2020: the 'Bombay cover' franked with two 1d 'Post Office' stamps hammered EUR 2,000,000 (>$2.5M with 20% premium). NOTE: figure is for the famous COVER bearing two 1d stamps, not a single loose 1d. Single-stamp benchmark (Feldman, Kanai sale, 1993): 1d orange = $1,072,260.

How this is made

The figure
One reference price, taken from a named public source and shown with its own kind. FLOAT does not average it with anything or adjust it for time.
Realized or not
A realized price is a completed sale. A market asking price and a price-guide value are not sales, and are labeled as such wherever they appear.
Why no grade ladder
Most FLOAT 100 entries are individual objects. There is one of this, so there is no population and no spread across grades to show.
