Imperforate
For postage stamps, separation is the means by which individual stamps are made easily detachable from each other. Methods of separation include: # perforation: cutting rows and columns of small holes # rouletting: small horizontal and vertical cuts # diecutting: cut paper to shape using a metal die—used for self-adhesive stamps. Early years In the early years, from 1840 until 1850, all stamps were issued imperforate, and had to be cut from the sheet with scissors or knife. This was time-consuming and error-prone (as mangled stamps of the era attest). Once reliable separation equipment became available, nations switched rapidly. Imperforate stamps have been issued occasionally since then, either because separation equipment was temporarily unavailable (in newborn nations for instance), to makers of automatic stamp vending equipment (the United States did this in the 1900s and 1910s), as novelties for stamp collectors (particularly when stamps are issued in souvenir ...

Penny Black
The Penny Black was the world's first adhesive postage stamp used in a public postal system. It was first issued in the United Kingdom (referred to in philatelic circles as Great Britain), on 1 May 1840, but was not valid for use until 6 May. The stamp features a profile of Queen Victoria. In 1837, British postal rates were high, complex and anomalous. To simplify matters, Sir Rowland Hill proposed an adhesive stamp to indicate pre-payment of postage. At the time it was normal for the recipient to pay postage on delivery, charged by the sheet and on distance travelled. By contrast, the Penny Black allowed letters of up to to be delivered at a flat rate of one penny, regardless of distance. Treasury competition On 13 February 1837, Sir Rowland Hill proposed to a government enquiry both the idea of a pre-paid stamp and a pre-paid envelope, a separate sheet folded to form an enclosure for carrying letters. Hill was given a two-year contract to run the new system, and tog ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

United Kingdom Postmaster General
The Postmaster General of the United Kingdom was a Cabinet of the United Kingdom, Cabinet-level Minister of the Crown, ministerial position in Her Majesty's Government, HM Government. Aside from maintaining mail, the postal system, the Telegraph Act 1868 established the Postmaster General's right to exclusively maintain electric Telegraphy, telegraphs. This would subsequently extend to telecommunications and broadcasting. The office was abolished in 1969 by the Post Office Act 1969. A replacement Statutory corporation, public corporation, governed by a chairman, was established under the name of the ''Royal Mail, Post Office'' (later subsumed by Royal Mail Group).

However the present-day Royal Mail Group was overseen by the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Philatelic Expertisation
Philatelic expertisation is the process whereby an authority is asked to give an opinion whether a philatelic item is genuine and whether it has been repaired or altered in any way. Forging and faking, regumming and reperforating of stamps is common in the philatelic marketplace, and increasingly buyers demand an expert certificate before buying a valuable item. Some items are so often faked or altered that they may be almost unsaleable without a certificate. The process of expertisation Experts may be individuals or committees but they will all follow a similar process to determine whether an item is genuine. The opinions of experts differ and have evolved over time. Conflicting expert opinions, such as on colour shade or whether a stamp has been reperforated, can have a huge effect on a stamp's value.''A Sharp Eye on collecting US Classics'' (Sharp Photography Publications, 2021) ASIN B091MBTGJ7 (read online) Stamps Experts will attempt to determine whether a questioned s ...

Perforation Gauge
In philatelic terminology, perforation gauge has two meanings: * As a term for classification. The "perforation gauge" of a stamp specifies the number of perforation holes that appear in a two-centimeter span along its edge. The finest gauge ever used is 18 on stamps of the Malay States in the early 1950s, and the coarsest is 2, seen on the 1891 stamps of Bhopal. Modern stamp perforations tend to range from 11 to 14. Many stamps are produced with "compound perforations" ''i. e.'', the vertical and horizontal perforations will be of different gauges. Many U. S. stamps have been perforated 10½ x 11. * As the name for a philatelic tool used to measure perforations. Invented in 1866 by Jacques Legrand, the typical "perf gauge" (sometimes called an odontometer) is a metal or plastic tile on which perforations of gauges ranging from 7 and 7½ to 16 and 16½ are marked (the marks sometimes appear at the edges of the tile). The philatelist places each of these depictions beside a stamp unt ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Postage Stamp Paper
Postage stamp paper is the foundation or substrate of the postage stamp to which the ink for the stamp's design is applied to one side and the adhesive is applied to the other. The paper is not only the foundation of the stamp but it has also been incorporated into the stamp's design, has provided security against fraud and has aided in the automation of the postal delivery system. Stamp catalogs like Scott's Standard Postage Stamp Catalog (SC) often document the paper the stamp is printed on to describe a stamp's classification. The same stamp design can appear on several kinds of paper. Stamp collectors and philatelists understand that a stamp's paper not only defines a unique stamp but could also mean the difference between an inexpensive stamp from one that is rare and worth more than its common counterpart. Making an accurate determination of the stamp's paper may require special tools such as a micrometer to measure the thickness of a stamp, certain fluid chemicals to re ...

Bhopal
Bhopal (; ) is the capital city of the Indian state of Madhya Pradesh and the administrative headquarters of both Bhopal district and Bhopal division. It is known as the ''City of Lakes'' due to its various natural and artificial lakes. It is also one of the greenest cities in India. It is the 16th largest city in India and 131st in the world. After the formation of Madhya Pradesh, Bhopal was part of the Sehore district. It was bifurcated in 1972 and a new district, Bhopal, was formed. Flourishing around 1707, the city was the capital of the former Bhopal State, a princely state of the British ruled by the Nawabs of Bhopal. Numerous heritage structures from this period include the Taj-ul-Masajid and Taj Mahal palace. In 1984, the city was struck by the Bhopal disaster, one of the worst industrial disasters in history. Bhopal has a strong economic base with numerous large and medium industries operating in and around the city. Bhopal is considered as one of the important fin ...
