On October 9 in New York, Robert A Siegel Auction Galleries will offer the Beverly Hills Collection of United States Invert stamps, starring the 1869 15c Pictorial invert.

This is the finest of just three recorded examples of the 15c invert, and an incredibly rare opportunity for major collectors

The collection comprises six of the US' rarest invert stamps, each of which has original gum and is among the finest recorded examples of its type.

The 15c invert will lead the sale, valued at $1.2m. With an intense rich colour and sharp impressions, the vignette is precisely centred within the frame and the fine details of the engraving are exceptionally clear, making this the finest of the three recorded examples.

Also from the 1869 Pictorial Issue is the 30c Ultramarine and Carmine stamp, which is also the finest of its kind. One of just seven examples, it is the only specimen with a small part of its original gum, warranting a $1m estimate.

Both of the 1869 stamps were once part of the world-renowned collection of George H Worthington.

The 1918 24c Inverted Jenny is a fabled stamp, possibly even the best-known rarity in the world

Also starring is the finest of five mint never-hinged examples of the famed 24c Inverted Jenny stamp, which is also valued at $1m. Originating from Position 68 from the only sheet ever found, the stamp boasts rich colour, full perforations and pristine gum, resulting in an unrivalled specimen of "philately's most renowned stamp".

Completing the sale are the finest known examples of the 1c, 2c and 4c inverts from the 1901 Pan-American issue, which are valued at $30,000,$120,000 and $75,000, respectively.

Paul Fraser Collectibles also houses some of the finest and rarest stamps for sale, including world-renowned rarities worthy of the greatest collections.
