The Series of 1851-57 10¢ Washington stamps were all imprinted in green ink utilizing a solitary plate. On the other hand, contrasts in the plate prompted four particular sorts with major Scott Catalog numbers. The Type I stamp can be distinguished by the left shell, which has external lines missing. The base right shell is finished. Its top external lines might likewise be inadequate.
Sorts
Sorts or mixtures happen when a stamp has contrasts that differ from the way it was initially proposed to be printed. These distinctions happen when the configuration is being exchanged to the plate for printing or when lines are re-cut.
The configuration is engraved on a pass on – a little, level bit of steel. The outline is duplicated to an exchange roll – a clear move of steel. A few impressions or “reliefs” are made on the roll. The reliefs are exchanged to the plate – an expansive, level bit of steel from which the stamps are printed. At the point when the configuration is being exchanged to the move or plate, contrasts can happen. A harmed plate or remote matter reasons contrasts. Lines re-cut on a well used plate can bring about two lines.
