Material Solid sterling silver (mixture of 92.5% silver and 7.5% copper) Availability Fountain pen Edition size 4,821 fountain pens Price $75 This pen was released in November 1965 and the silver used to make this pen's cap and barrel came from a sunken Spanish galleon in an armada of 11 ships. The ship was carrying gold and silver treasures from the new world back to Spain and King Philip V. After the two groups of ships left Vera Cruz and Cartagena, they gatd in Havana to form an armada and head northward on the gulf stream. Seven days after leaving port, on July 31, 1715, the armada encountered a hurricane. 10 of the 11 ships sunk off the coast of Florida. To coin collectors, this group of shipwrecks became known as the 1715 Plate Fleet. The silver was salvaged in 1961 by Mel Fisher who had the backing of investors including Ken Parker. Parker was struck with the brilliant idea to create a limited edition Parker 75 using the salvaged silver. The pen was packaged in a unique kit. The complete kit consists of: Wooden gift box whose exterior contained a map of the doomed ship's route and location w it sank. The inside cover had another map showing the layout of the ship and the location of the treasure it stored. Certificate of Authenticity with an impressive and official-looking seal by a Florida notary public attesting to the source of the silver. Normal Parker 75 booklets. White outer cardboard box with price tag. The pen has some impressive engravings. Around the cap band was an engraving to commemorate the source -- "STERLING SILVER - SPANISH TREASURE FLEET - 1715" -- in addition to the normal Parker logo and "Made in U.S.A." The tassie on top of the cap had the mark of the mint of Mexico, the letter M with a small circle over it. And on the tassie at the bottom of the barrel is engraved the Eagle of Purity, insignia for King Philip V of Spain. The weights of the cap and barrel of this pen without the section, nib, or converter are 8.5 and 10.0 grams, respectively. After issuing this limited edition, Parker sent their dealers a plastic package containing a replica doubloon with a description on parchment. Thus was born the first limited edition fountain pen the US has ever seen! This kit includes the doubloon, but not the parchment description.
