Collectibles can serve as miniature time capsules, preserving history in tangible form. Take the "Inverted Jenny," for example – a 1918 U.S. postage stamp that accidentally featured an upside-down biplane. This misprint, valued over $1 million, reflects both human error and the infancy of airmail. Each collectible, be it a stamp, coin, or toy, is not just a relic but a snapshot of the cultural, political, or technological landscape of its era. What collectible holds a special story for you?
