Unveiling the World's Most Valuable Collectors' Items

17. The OG Sony Walkman (Original Price: $200* Worth Today: $951*)

The Walkman was a game-changer that brought Sony huge success. When it hit the market in 1979, this portable audio player carried a hefty price tag of $200 (which would be close to $800 in today's dollars). Since then, a staggering total of approximately 385 million units have been sold, solidifying the Walkman's status as a pioneer in portable music technology.

The world of tech nostalgia holds great value for collectors. Vintage Walkmans from the late 1970s can fetch up to $1,000 today, despite their mass production at the time.
