Chicago Coin was one of the early major manufacturers of pinball tables founded in Chicago, Illinois. The company was founded in 1932 by Samuel H. Gensburg to operate in the coin-operated amusement industry. In 1977, Gary Stern and Sam Stern purchased the assets of the Chicago Coin Machine Division as it was then called to found Stern Electronics, Inc. They also produced various arcade games during the 1960s to 1970s. History Sam Gensburg founded Chicago Coin Machine Exchange with brother-in-law Sam Wolberg and third partner Lou Koren, a company which had a business of trade-ins for coin-operated games. In 1931, Sam Genburg's brothers Louis Gensburg, David Gensburg, and Meyer Gensburg had founded Genco as an amusement manufacturer and Samuel decided to enter that business by establishing Chicago Coin Machine Exchange. The company started off by making replacement boards for early pinball games before creating the table Blackstone (1933) which was manufactured by a partner named Stoner. In 1957, the company changed its corporate name to Chicago Dynamic Industries, retaining Chicago Coin as a label of the company. Genco would remain a competitor with Chicago Coin until the companies merged in 1959. Though never a technologically-driven or innovative company, Chicago Coin was highly successful in the years preceding and immediately succeeding World War II. Their pinball table Beam-Lite (1935), which featured a lighted playfield, sold 5,703 units and their flipperless game Kilroy (1947) sold 8,800 units which was the highest selling pinball table up until the 1970s. The company also diversified in later years, creating sports tables and shuffle alleys. 1960s They later manufactured various other electro-mechanical games (EM games) for amusement arcades. In 1969, they manufactured Speedway, a licensed North American version of racing game Indy 500 (1968) from Japanese company Kasco. It resembled a prototypical arcade racing video game, with an upright cabinet, yellow marquee, three-digit scoring, coin box, steering wheel, accelerator pedal, and pseudo-3D first-person perspective. While Kasco's original Indy 500 had sold over 2,000 arcade cabinets in Japan, Speedway went on to sell over 10,000 cabinets in North America, making it the biggest hit arcade game in years, and setting an arcade sales record that was not surpassed until the arrival of arcade video games in the 1970s. Like Sega's Periscope (1966), Speedway also charged a higher US quarter price point per play, further cementing quarter-play as the standard for North American arcade games for over two
