The French also established today’s court ranking of king, queen, and valet or knave. Originally, the king was the top-ranking card, though games began giving the highest status to the ace by the 17th century. In 1565, Frenchman Pierre Marechal illustrated the set of reversible court cards with intricate designs showing figures turning to the side and holding weaponry, scepters, and flowers. This imagery would later be copied by most British and American manufacturers, and evolved into the standard characters seen on face cards today.
These early playing cards were hand-painted, often with gilt detailing, and designed to be beautiful objects. Meant for gambling as well as playing games of skill, they also typically incorporated symbols or mnemonics to represent knowledge ranging from botany to heraldry, cosmology to geography.
During the 1700s, Edmond Hoyle got his start by tutoring affluent players in the art of “Whisk,” the most popular card game in England at the time. Hoyle printed a manuscript on the game and his personal strategies, which was copyrighted and published as a book in 1742. Soon Hoyle was the top name in cards, and even after his death in 1769, all manner of rule books and playing card decks were printed with his name in the title.
After reviewing several sites these cards hold a rough value of $5000.00 or more. The condition quality and under glass make these highly collectible as they are rare to find in such good condition.
