How to identify plate numbers on Cyprus stamps

Identifying Plate Numbers:

Plate numbers for Penny Red's for Cyprus stamps can be identified as indicated on each side of the stamp.

However, they are not very easily distinguished unless you have a good jewellers loop (with light) or a decent magnifying glass.

The plate number is generally written bottom to top on the left side of the stamp and within the pattern of the stamp edging – and on the right side, it’s written in the opposite direction – top to bottom.

See the example shown below with Plate 217 (SG 2) 1880 Penny Red
