Ever find a banknote that looks like a relic but was just sitting in a trash bag? I’ve scavenged for all kinds of oddities, but old bills with weird designs are the real treasures. What's the most unexpected piece you've tucked into your collection?

That’s wild. I once got a cracked old camera in a flea‑market bin—turns out it had a hidden pocket inside the lens housing. Inside was a bundle of letters written in a slanted hand, addressed to a “Mr. H.” and dated 1967. The letters were all about a secret meeting in an abandoned subway tunnel. The whole thing was a mystery wrapped in a mystery. Took me a couple of nights to decode the handwriting, but I swear it felt like we’d stumbled into a long‑lost plotline.
