You Won't Believe How Much These Collectibles Fetched at Auction

Thanks to eBay, a lot of people have made a healthy profit by cleaning out their basements and attics. On the other hand, collectors have gone broke submitting winning bids to own these rare items. We've found some of the most surprising sales of otherwise common items, not only on eBay but from professional auction houses, too. In some cases, a company made a one-of-a-kind item designed to fetch a high price, but most are collectibles that grew in value naturally.

The Dunes hotel and casino in Las Vegas was demolished in 1993, but some of its playing cards are still around. On Aug. 15, 2018, a set of two decks sold for $2,500 making them worth $1,250 each.

When you just can't commit to one cereal for the whole week, Kellogg's and General Mills offer variety packs where you can choose a different cereal every day. What you can't find anymore is the Post Ten pack. One surviving pack from 1961 fetched $2,550 on eBay. Let's hope the buyer didn't eat it. Another sweet item satisfies two sets of collectors: Beatle maniacs and cereal collectors. The Beatles were featured on boxes of Rice Honeys cereal to promote Yellow Submarine. If you saved one of those boxes, they're going for over $1,000. In 2014, someone sold one for $1,430.50 at Heritage Auctions. The 50-year-old cereal was not included, but it did include the prize inside, a set of rub-ons. There were originally eight total, but this collector had six.

Historic daggers, swords, and other blades can go for millions, especially if previously wielded by historical figures. Bob Loveless was a prestigious blade maker and this classic Loveless fetched over $20,000 (although not the full $30K the seller had originally asked). This blade was made in the 1950s during Loveless' time in the Merchant Marine.

Every once in a while, a can of Coke comes off the assembly line empty, but still sealed. Don't open it! These rarities periodically turn up on eBay, and have sold for as much as $250,000 according to Buzzfeed and Nailbuzz.

Collecting vinyl has made a comeback since true audiophiles prefer the physical media to CDs or digital. While first pressings of classic albums can be worth a lot, you really can't beat the very first record of The Beatles' White Album owned by Ringo Starr himself. (A copy of Wu-Tang Clan's "Once Upon a Time in Shaolin" sold for $2 million, but there are no other copies of that album.)

In 2008, businessman Saeed Abdul Ghafour Khouri paid 52.2 dirham ($14.3 million U.S.) for a license plate, just so he could have the number 1. Now, did anyone save the U.S. license plate number 1?
