15. 1977: Star Wars Figurines
Fun Fact: The demand for Star Wars action figures was incredibly high around the holidays in 1977, so Kenner created an "early bird" package, which means kids could send away for the first four action figures and receive them in early 1978. After that, 8 more action figures were released. These original figurines retailed at $9.99 and are now worth a ton of money.
