Kenya 1975 Seashells Definitive Stamps with New Value Overprints

Kenya · 1975 · 1.50/-, 2.50/-, 2.50/- Kenyan Shillings

This set of three definitive stamps from Kenya, issued in 1975, features detailed illustrations of various seashells: Charonia tritonis, Fasciolaria trapezium, and Pterocera scorpio. Each stamp has been overprinted with a new postal value (1.50/-, 2.50/-, 2.50/-) on the original 2/-, 3/-, and 40/- denominations.

Overprints were a common method for postal authorities to quickly adjust stamp denominations in response to currency changes or revised postal tariffs, avoiding the need for entirely new printings. These overprints reflect such adjustments in Kenya's postal system during the mid-1970s.
