“Seahorse” High Value – Great Britain 1913

Part of the Iconic Stamp series. Click here to see the full list of Iconic Stamps.

First issued in June and August 1913, on the cusp of World War 1, the definitive high value “Seahorses” remain one of the most iconic stamps to date. This is primarily due to their high quality engraving and intricate design, a depiction of Britannia on her chariot behind three horses on a rough sea, accompanied by a striking portrait of King George V.

These elegant stamps were designed by the renowned Australian sculptor, Bertram Mackennal, who at the time strongly recommended that they be printed by the intaglio process to make them even more distinguished. The stamps were issued in four colours and values: brown (2s 6d), red (5s), blue (10s) and green (£1).

During this turbulent era of war and economic turmoil the stamps were issued as a symbol of patriotism and camaraderie; they depicted Britain as a powerful country ‘and a ruler of the seas’. The longevity of the issue, coupled with the powerful Britannia design, explains why they are so popular with collectors.

Did you know...

  • The Seahorses were in circulation longer than any other British high value stamp.
  • Four contractors were used to print over 100 million of these stamps, from over 50 individual plates. Sadly the archive of one of the contractors (Bradbury Wilkinson) was incinerated on the instructions of the management.
  • The Seahorses were overprinted for use in Bechuanaland, British Levant, Ireland, Morocco Agencies and Nauru.
  • Very fine used Seahorses, neatly cancelled, and well centred with a good colour are far scarcer than their mint equivalents.

What our customers say...

“I would choose the 1913 £1 Seahorse. In my opinion this is the best stamp design ever issued, and the seahorse theme is very appropriate for travels abroad!”
– Alan Ottiwell

“KGV Seahorse £1. This stamp is a universally recognised face of British unity and strength of purpose through its striking use of Britannia astride her chariot, a Union Jack on her shield.”
– David Collingridge

“The GV Seahorses. The stamps contain a dramatic scene and are intricately engraved. The most beautiful of all GB stamps, which should be promoted to inspire people to investigate and take up philately.”
– Steve Waldron

Discovering Seahorses

A product of six years’ research, Discovering Seahorses relates the story behind the creation of the Seahorses, and the changes they experienced during their production over a period of 26 years.

Little is known about their varieties and ever since they were issued, 90 years ago, the technical and philatelic aspects of the King George V Seahorse stamps have remained undiscovered. For the first time, all their plates and the quantities printed are identified. The numerous shades are explained and all plate varieties are illustrated and included in the next Specialised Catalogue.

This comprehensive guide will help collectors have a better understanding of the details unknown still to some and will allow philatelists uncover the rich history behind their existence.
