We all saw the viral images of the McDonald’s fries that were left in someone’s car for ages and didn’t collect mold. The fries earned some online fame for 15 minutes but weren’t worth any cash. This pack of sauce was forgotten in someone’s car since 1998 (!!) and not only did it not go rotten, but it somehow became worth a small fortune. 

The McDonalds ‘Mulan’ Szechuan Sauce was released as a limited-edition sauce when the film came out in 1998. In 2017 as part of a publicity stunt, the creators of Rick and Morty caused a buzz online with a petition to bring back the sauce. Following the sensation, an eBay buyer forked out a whopping $14,700 for the old sauce. 

It may seem like a crazy move to most of us, but clearly this buyer was driven by a passion for taste. McDonald’s memorabilia is a strange and interesting niche in the collecting world that often defies logic – but therein lies the charm!
