The $100 Prop That Became Worth $10,000

This ordinary item sat on a studio shelf for years, gathering dust.

It's just a simple coffee grinder, costing maybe $100 back then. But this wasn't

just any coffee grinder. It was a background prop in the legendary movie,

Back to the Future. As the film became a timeless classic,

something magical happened. This forgotten prop became a symbol of cinematic history. Today,

that $100 coffee grinder can fetch over $10,000 at auction. All thanks to

the power of nostalgia.
