These plates were released by Royal Cornwall in conjunction with the Calhouns Collectors Society in the early 1980s. There were ten plates in the series by artist Alan D’Estrehan. The edition was limited to 19,500 sets and each plate is 9 1/4” in diameter with a 24k gold rim. Each plate in Royal Cornwall’s Legendary Ships of the Seas series is hand-numbered on the back in gold and includes the artist’s signature, plate title, and name of the collection. $40 for all three.
