The Stanley Cup (French: La Coupe Stanley) is an ice hockey club championship trophy, awared annually to the National Hockey League (NHL) playoffs champion. It is commonly referred to as The Cup, The Holy Grail, or facetiously (chiefly by sportswriters) as Lord Stanley's Mug. The Stanley Cup is surrounded by numerous legends and traditions, the oldest of which is the celebratory drinking of champagne out of the cup by the winning team. Unlike the trophies awarded by the other three major professional sports leagues of North America, a new Stanley Cup is not made each year; Cup winners keep it until a new champion is crowned. It is the only trophy in professional sports that has the name of the winning players, coaches, management, and club staff engraved on it. The original bowl was made of silver and has a dimension of 18.5 centimeters (7.28 inches) in height and 29 centimeters (11.42 inches) in diameter. The current Stanley Cup is made of silver and nickel alloy. Today, it has a height of 89.54 centimeters (35.25 inches) and weighs 15.5 kilograms (34.5 lb).
