The centuries-old reason why coins have ridged edges
0
·1 viewsThe ridged edges found on coins were introduced centuries ago as a measure to prevent theft of precious metals from currency. Dishonest individuals would shave or clip the edges of metal coins to collect valuable material while keeping the coins in circulation. By adding ridges, authorities could easily detect any tampering, since shaving would remove the pattern. In modern times, ridged edges serve additional purposes, including helping people identify coins by touch and improving grip. They also play a role in contemporary anti-counterfeiting efforts, making coins harder to replicate fraudulently.
