#3: Post Honeycomb Spy Decoder Rings (1960s)
Honeycomb cereal always had a rich, honey taste back in the day. Their cereal prize was something you had to win in a sweepstakes, and it was no cheapie! This ring was 24 carats, meaning adults would love it, too. I’d probably lose this thing if I were a kid. Since it’s a rare prize item, it’s not something you can easily buy. But it has been auctioned before for $293. Honestly, I thought it’d be worth a little more.
