A Spalding Hi-Bounce Ball, often called a Spaldeen, is a small rubber ball, somewhat similar to a racquetball, and supposedly made from the defective core of a tennis ball without the felt. It was the more expensive and more popular version of the Pensie Pinkie (made by the Penn tennis ball company). These balls are commonly used in street games developed in the mid-20th century, such as Chinese handball (a variation on American handball), stoop ball, hit-the-penny (involving trying to make a penny flip on a sidewalk), butts up, box ball, punchball, half-rubber, and stickball (a variation of baseball).
The term most likely arose from a New York City-accented pronunciation of Spalding, the sporting goods company that produced the balls. It may also have originated with a mis-reading of A. G. Spalding's signature on the ball. The name has become so common that Spalding now uses it in marketing, and it is now a registered trademark.
Spaldeens were popular with children from the 1930s through to the 1970s. In urban areas sparse in grass, Spaldeens became integral to many street games due to their bounciness and light weight. Citing the declining popularity of stickball, Spalding took the ball off the market in 1979, but it returned in 1999 to much fanfare. The retail price in the mid-1960s in Jersey City was 29 cents.
In the documentary New York Street Games, celebrities including Whoopi Goldberg discuss their memories of games they played as children growing up in New York City. Many of these games involved Spaldeens.
In the television series Weeds, Shane's grandfather tells him that, "Real Estate always bounces back. It's like Spaldeens. You know what Spaldeens are? Well, they bounce..."
In the television series Law & Order, Season 4, Episode 9 - Adam Schiff tells a story of getting into a fight with a kids when they were both young, and having his spaldeen thrown down a sewer.
