One Penny Plate 1
Plate 1 is iconic, being the first plate from which postage stamps were printed. The stamps were put on sale on 1 May 1840 and available for postage from May 6. However, by this time the plate was already showing significant signs of wear. Printing was continued until May 16 after which it was replaced by Plate 4. Plate 1 was then extensively repaired by re-entering every impression, thus creating a second state for every stamp. The initial printing is known as Plate 1a and the first repair Plate 1b. Printing from Plate 1b commenced on May 26.
This display looks at the early issues from Plate 1a and how later issues developed a worn appearance necessitating the major repairs. The differences between the two states are shown and examples provided of re-entries and double letters. Finally examples in brown are shown with an impression from State 1c.
