Unveiling the World's Most Valuable Collectors' Items

31. 1980s The Simpsons Bedding (Original Price: $20-$50* Worth Today: $175*)

The Simpsons is hands down one of the most successful franchises ever, whether you're talking about animated shows or anything else. Those iconic yellow characters have graced countless merchandise items, and some of them are worth a pretty penny. Take, for example, The Simpsons bedding from the 1980s, which can fetch up to $175 for collectors.

But it's not just the '80s that have value. Even stuff from the early 1990s can make you some serious cash. Just look at a three-piece twin sheet set from 1990 currently listed on eBay for $175. Keep in mind that the price will vary depending on whether the sheets are new or used, but even if they're pre-loved, you might still make a nice profit.
