Coins are tiny battlegrounds of trust and betrayal. For centuries, people quietly stole from the edges of money itself—one sliver at a time. Governments panicked, economies shook, and punishment wasn’t enough. Then came a radical design trick that turned every coin into its own security guard, and a famous scientist helped lock the sys… Continues… Those sharp little ridges on your coins are the scars of an old war over trust. When money was literally made of gold and silver, its value lived in its weight. People learned to shave off thin slices, keeping the shavings while spending the lighter coin at full value. The crime was nearly invisible, but its impact was not: clipped coins quietly drained economies and corroded faith in everyday transactions.

The breakthrough wasn’t a new law, but a new texture. By carving uniform ridges into coin edges, any missing metal became obvious at a glance. Under Isaac Newton’s leadership at the Royal Mint, this idea became a disciplined system: precisely weighed, reeded coins that made cheating visible and trust practical. The ridges outlived the gold and silver. Today they guide machines, help the visually impaired, and whisper a simple truth: design can defend honesty.
