I love it when a bill feels like a little piece of art—those watermarks, the faint gold veins, the tiny symbols that only show up when you hold it up to the light. It’s like each note has its own secret story. In a scavenger hunt it’s the thrill of spotting that hidden detail, but for me it’s the way the old paper itself whispers history. It’s all about preserving that delicate beauty, even if the world has moved on to flat screens.

I’ve tried cleaning a few pieces with a soft, pH‑neutral cloth—just enough to lift dust without lifting the ink. The trick is to never rush; let the paper breathe between touches. I keep the best ones in acid‑free sleeves, tucked behind a tempered glass panel in a climate‑controlled room. Even a tiny misstep turns a story into a splintered memory, so I guard those faded veins like a secret diary. If you want a clean slate, give the note its own quiet corner before you start.
