Invert
Also: inverted centre, inverted frame, inverted overprint, Inverted Jenny
An invert is a stamp error in which part of the design — such as the centre vignette, frame or overprint — is printed upside down relative to the rest of the stamp.
Glossary Term
Tête-bêche describes a pair of joined stamps in which one stamp is printed upside down or sideways relative to the other.
Also known as: tete-beche, tête-bêche pair, head-to-tail
Tête-bêche (French for “head-to-tail”) describes two stamps that are still joined, with one upside down or sideways in relation to the other. The pair must remain attached: a single stamp cannot be tête-bêche on its own.
By error. On early printing plates assembled from individual clichés — separate small printing units for each stamp — a cliché could be inserted the wrong way up. Every sheet printed from that plate then contained an inverted stamp, producing tête-bêche pairs with its neighbours. The 1849 Ceres issue of France includes famous tête-bêche errors of this kind, and they are among the classic rarities of French philately.
By design. Many stamp booklets and sheet formats are laid out so that stamps are printed tête-bêche — for example, when two rows are printed head-to-head to fit a booklet’s folding pattern. These deliberate tête-bêche pairs are common and inexpensive, although collectors still seek them out as distinct items.
Some issues produce tête-bêche pairs across a gutter, with the stamps on either side of the gutter facing opposite directions. These are collected alongside ordinary gutter pairs.
Tête-bêche material is listed in major catalogues, often with separate values for pairs, blocks and gutter pairs. Like se-tenant combinations, tête-bêche pairs must be kept intact and stored in mounts or stockbook strips wide enough to hold them without folding.
It is French for 'head-to-tail'. In philately it describes two joined stamps with one inverted, or turned sideways, relative to the other.
Some are errors, caused when a single cliché was inserted upside down in a printing plate. Others are deliberate, created by booklet or sheet layouts. Error tête-bêche pairs from classic issues are rare and valuable.
Never. Once separated, the two stamps become ordinary singles, and the tête-bêche status — and most of the value — is lost.
