Break into leaf of stamps

A sheet of stamps is a form of sale of the postage stamps. These sheets generally include/understand two panels which on the whole comprise hundred or two hundred stamps. Even not notched, these sheets make it possible to easily provide to the customer the number of specimens wished.

Edges of sheets

The edges of sheet of stamps rather often white and are detached by the users to be able to stick the stamps on their folds.

It is on these edges that mentions of control of printing works are printed: number of the rotary printing-press, goes back to impression, number of the sheet, facial value total and the unit, etc This information makes it possible to discover variations in the impression of a stamp, everyday usage in particular, and to determine the scarcity of it, therefore the value. The variations can be a color changing of tone, a repetitive anomaly (a point of color), etc

These edges of sheet can as be printed drawn reasons, in a preoccupation with a decoration or simply to prevent as pieces of paper gummed are used for the forgers. In France, the edges of certain sheets of commemorative stamps are printed of a reason as soon as they have a dimension close to a postage stamp.

In Israel, since 1948, the lower edges of the sheet are systematically printed with a reason or a text clarifying the subject of the postage stamp. A stamp himself-holding with this label called is more required than the stamp alone.

The block-layer

One speaks about layer or block-layer when the sheet presents a block of some stamps (to the maximum a score). The purpose of the block-layer is often to be collected by the philatelists, and thus not to be used. In the Anglo-Saxon countries, the postal administrations speak explicitly about blocks and notebooks “of prestige”, the sumptuous presentation (illustration…) by making an object of collection.

To support the sale of sheet of stamps with strong facial value, like the stamps of Airmail often expensive, the stations emit layers of ten specimens to the decorated margins.

Collection

Certain philatelists collect the stamps by whole sheet. That avoids to them having the more or less damaged teeth their stamps. They especially hope for that with time the commercial value of these sheets will increase because of their scarcity, few collectors being able to allow itself to finance the purchase of such a collection. In January 2001, for the passage to the Euro, La Poste Frenchwoman proposed a philatelic leather memory including/understanding a sheet of one hundred stamps Marianne of July 14th to 1 frankly and a sheet of stamps with 1 euro; sold with the facial value, it cost 115,24 euros.

Other collectors get only the dated corners, these corners of sheets carrying the date of impression or information on the used rotary printing-press. They are thus satisfied with ten or score of stamps and nonprinted band carrying the date. That then makes it possible to study the types and the varieties of a stamp and to determine the dates of the changes of punches (type) and faulty impressions (variety).

In Israel, as of the first emissions of 1948, the postal administration prints a legend illustrated on the lower margin of the sheet. Called tabs , these labels himself-holding with the stamps of the last line are sought by the collectors.

Boarding

Certain collectors practice the boarding : they try to reconstitute the sheets of some stamps of everyday usage. That is allowed by light repetitive differences.

For the lithographed stamps , the carryforward of the stereotypes of the board of impression starting from an original drawing is never perfect. The light differences on a stereotype are deferred on the stamps of the sheet always in the same box.

In Copper-plate engraving, the boarding of the first British stamps (as the Penny Black) is an activity made possible by the letters registered in the corners and by a number of board discreetly placed in the Gravure of the stamp.

Anecdotes

Before the end of the Second world war, conscious that the mode marionette of the State independent of Croatia of the local dictator Ante Pavelić, was going to crumble, considering military progress of the troops of Tito, certain dignitaries of this mode imagined to make block-layers, emitted with very small pulling by the post office of this state. This in order to constitute negotiable scarcities thereafter. When Croatia was released by the titists, the workmen of the presses of the printing works of the stamps warned the new Masters of the Yugoslavia. Order, then was given to realize, on the same presses, with same papers and same inks of innumerable quantity of these blocks and to flood the philatelic market of it, thus ruining the operation. The blocks titists being indistinguishable first blocks.
