USA 2001 Pan American Inverts Miniature Sheet

Issue date 29 March 2001

The US Postal Service issued The Pan-American Inverts souvenir sheet in New York, New York, on March 29, 2001. 

The Pan-American Exposition (May 1, 1901-November 2, 1901), held in Buffalo, New York, highlighted advancements of the nineteenth century in industry, transportation, manufacturing, and the arts. On opening day, the US Post Office Department issued a series of six bi-colored stamps commemorating the exposition, using the theme of transportation. A limited number of the stamp sheets were printed with inverted centers: the 1-cent stamp depicting the steamship, "City of Alpena"; the 2-cent stamp depicting the train, "Empire State Express"; and the 4-cent stamp depicting an early electric automobile. The rare inverts quickly became collectibles.

This 2001 souvenir sheet includes reproductions of these famous Pan-American inverts in their original colors as well as four reproductions of a "cinderella" that originally commemorated the 1901 Pan-American Exposition. (A cinderella is an item that resembles, but is not, an official government-issued postage stamp.) The design of the red and blue, diamond-shaped cinderella features a charging buffalo in the center encircled by the words "Pan- American Exposition Buffalo." The addition of an 80-cent denomination makes each of the four cinderella reproductions official postage stamps.

A detail of the cover illustration from a 1901 souvenir guide also appears on the 2001 souvenir sheet. In the illustration, an allegorical female representing unity among the Americas stands on top of a globe. In her left hand she holds a flag - half Canadian, half American - and her right arm rests on the back of a buffalo. The globe shows the western hemisphere and includes the words "Pan-American Exposition 1901. Buffalo, NY, USA." Niagara Falls appears in the background.

The right side of the souvenir sheet shows a map of the northeastern United States that focuses on the route of the first regularly scheduled Air Mail service in May 1918. 

A compass rose, a common element on maps and nautical charts, appears in the lower right corner.


A banner above the two rows of three Inverted Jenny stamps reads “STAMP COLLECTING.” Beneath it, upside down, is a similar banner reading “INVERTED JENNY.”

A twist in the tale to the issuance of this Souvenir Sheet, there have been news report that in order to draw more people to collect stamps, the US postal authorities have randomly distributed 100 sheets inserted among 2.2 million souvenir sheets featuring the plane right-side up with one last listed online for $25000.

Austria 2009 The Pearl of Philately Stamp with half pearls affixed

Issue date 06 May 2009

From May 6 to May 10, 2009, Essen (Germany) simultaneously hosted the International Philatelic Exhibition (IBRA), the National Stamp Exhibition (NAPOSTA), and the 19th International Stamp Fair. An Austrian Post issued p-stamp (Personalised Stamp) issued on the occasion of philatelic exhibition ' IBRA - NAPOSTA ' 09 ' in Essen ( Germany ).

The p-stamp features  a half pearl affixed on the stamp surrounded by the other philatelic pearls or you could say legends on stamp collecting. The legendary stamps featured on this stamp are

- The rare Mauritius Two Pence Blue(1847) which was one of the star attraction at the philatelic exhibition at Essen. According to the legend, Barnard had engraved "Post Office" instead of "Post Paid" by mistake. The latter appellation was to be seen on all Mauritian stamps during almost twenty years. Much later it was proved that "Post Office" was really the legal term used for the Post in those days.

The "Mauritius Post Office" stamps have become rare gems of world philately. They are in fact the first Mauritian stamps, among the very first in the world. They are also among the rarest because only 500 of these stamps were printed for the Mauritian Post.

- The Basel Dove Stamp The Basel Dove Stamp is one of the world’s first tricolor postage stamp. The stamp was issued on July 1, 1845 by the Canton of Basel (member state of the federal state of Switzerland). It has a face value of 2 ½  rappen and was the only stamp issued by Basel. It is the world’s first tricolor stamp printed in black, crimson, and blue. The stamp was designed by Melchior Berri which featured a white embossed dove carrying a letter in its beak, and inscribed with “STADT POST BASEL” 

- The first stamp of Saxony (Sachsen in German), issued in 1850, shown above, is one of the rarest of classical European stamps.  An estimated 3,000 to 4,000 copies are thought to exist today, and many of them are repaired. This is also one of the most forged of the classical European stamps, most notably by Fournier. 

- The Three Skilling Yellow (1855) , a rare color error of the first stamp from Sweden

- The  'Inverted Jenny' Error stamp from USA (1918)

Gambia 2004 Rare and Famous Postage Stamps miniature sheet featuring the inverted Jenny

Issue date 04 June 2004

The miniature sheet issued by Gambia Post features a Stamp on Stamp of the Inverted Jenny which is one of the category under which this miniature sheet is filed.

The Inverted Jenny (also known as an Upside Down Jenny or Jenny Invert) is a United States postage stamp first issued on May 10, 1918 in which the image of the Curtiss JN-4 airplane in the center of the design appears upside-down; it is probably the most famous error in American philately. Only one pane of 100 of the invert stamps was ever found, making this error one of the most prized in all philately. 

The British Guiana 1c magenta is regarded by many philatelists as the world's most famous stamp. It was issued in limited numbers in British Guiana (now Guyana) in 1856, and only one specimen is now known to exist.

The Penny Black was the world's first adhesive postage stamp used in a public postal system. It was issued in Britain on 1 May 1840, for official use from 6 May of 1840.
The idea of an adhesive stamp to indicate pre-payment of postage was part of Sir Rowland Hill's 1837 proposals to reform the British postal system; it was normal then for the recipient to pay postage on delivery. A companion idea, which Hill disclosed on 13 February 1837 at a government enquiry, was that of a separate sheet that folded to form an enclosure or envelope for carrying letters. At that time postage was charged by the sheet and on the distance traveled.

The Benjamin Franklin Z Grill, or simply "Z-Grill", is a 1-cent postage stamp issued by the United States Postal Service in February 1868 depicting Benjamin Franklin. While stamps of this design were the common 1-cent stamps of the 1860s, the Z-Grill is distinguished by having the so-called "Z" variety of a grill pressed into the stamp, creating tiny indentations in the paper. The 1-cent Z-Grill is generally cited as the rarest and most valuable of all US postage stamps.

There are currently only two known 1-cent 1868 Z-Grills, both with cancellation marks. One is owned by the New York Public Library as part of the Benjamin Miller Collection. This leaves only a single 1-cent 1868 Z-Grill in private hands.

5-cent red brown stamp depicting Benjamin Franklin (the first postmaster of the U.S.) - The first U.S. Postage stamp issues were authorized by an act of US Congress and approved on March 3, 1847. The earliest known use of the Franklin 5¢ is July 7, 1847.

This stamp were declared invalid for postage on July 1, 1851.

Subcategory - Stamps on Stamps  - Inverts

In philately, an invert error occurs when part of a postage stamp is printed upside-down. Inverts are perhaps the most spectacular of a postage stamp errors, not only because of the striking visual appearance, but because they are almost always quite rare, and highly valued by stamp collectors.

Inverted Jennies have long sold for over 100,000USD apiece, and the St. Lawrence Seaway inverts of Canada approach those numbers.

The Inverted Jenny (or Jenny Invert) is a United States postage stamp first issued on May 10 1918 in which the image of the Curtiss JN-4 airplane in the center of the design was accidentally printed upside-down; it is probably the most famous error in American philately.

Other know invert errors are
- United States - 2 cents - inverted train from the 1901 Pan-American Exposition series
- Austria - 2 kronen - inverted parliament building from the 1919    definitive series
- New Zealand - 4 pence - inverted tropical scene from the 1902 definitive series

The following are Stamps which feature the inverted stamps.

India 2012 – Philately Day Stamp showing ‘The Inverted Head 4 Annas Stamp’

Issue date 12 October 2012

India Post issued a Souvenir Sheet to mark Philately Day and to commemorate Philately. The souviner sheet marks the Indian Postal system evolution from the 'Dak Harara' (Postal Runner) to 'Airmail' and showcases two iconic stamps issued pre and post Independence era. 

The first stamp 'The Inverted Head Four Anna Stamp' was first issued in 1854 which was one of the world's first multi-colored stamp. The second stamp shows one among first three 'Jai Hind' Stamps issued post Independence. This Stamp was issued in 1947 and depicts the national emblem of India.

The Inverted Head Four Annas of India is a postage stamp prized by collectors. The 1854 first issues of India included a Four Annas value in red and blue. However, an invert error occurred during production, showing the head "upside down." This error appears not to have been discovered until many years after the stamps were issued. None of the 1870s publications mentions the Inverted Head Four Annas. The 1891 reprints provide the first conclusive evidence that the error was known.

The error was first noticed during a meeting of the Philatelic Society of London in 1874. In 1907 L.L.R. Hausburg mentioned the Inverted Head Four Annas, but he was not sure whether it came from the First or Second Printings. Mr. Séfi described this error in the West End Philatelist, January, 1912.

Qu'aiti State in the Hadhramaut, South Arabia (now a part of Republic of Yemen) 1967 STAMPEX - London, England Philatelic Exhibition

One of the stamps of 5 fils features India - 4 annas - inverted head of Queen Victoria from the 1854 definitive series.
