In Italy’s Emilia-Romagna region, a traditional bank called Credito Emiliano lines its coffers with edible gold. As Great Big Story reports, the financial institution accepts parmigiano-reggiano (Parmesan cheese) as collateral for loans, in addition to conventional currencies.

Emilia-Romagna is a major producer of parmigiano-reggiano, which is a hard, dry aged cheese made from skim milk. (Similar to how sparkling wine can only be called Champagne if it was made in the region of Champagne, France, Emilia-Romagna is the only region in the world that can legally use the parmigiano-reggiano name.) Not surprisingly, the cheese is a lucrative local commodity: Wheels of parmigiano-reggiano can be worth thousands of dollars, making the food a safe bet for banks looking to lend money to cheese producers. And conveniently, parmigiano-reggiano needs to be aged anywhere from 18 to 36 months, so it's ideal for long-term investments.

To keep the cheese safe (and delicious), Credito Emiliano stores it in a local warehouse. “We protect the producer’s investment, basically from cow to bank,” jokes Roberto Frignani, the warehouse’s general director.
