The Richter Scale, developed by seismologist Charles F. Richter in 1935, revolutionized earthquake measurement by providing the first standardized method to quantify seismic energy. A new commemorative silver coin issued on behalf of Niue celebrates the 90th anniversary of Mr. Richter’s development of this crucial piece of tracking equipment. Today, 2025 1 oz Proof Colorized Niue Richter Scale 90th Anniversary Silver Coins are available at JM Bullion.

While working at the California Institute of Technology, Richter created a logarithmic scale where each whole number increase represents a tenfold increase in measured amplitude and roughly 32 times more energy release. The scale was initially calibrated for Southern California earthquakes using specific seismograph equipment, making it a regional tool that proved remarkably effective for comparing earthquake magnitudes.

All 2025 1 oz Proof Colorized Niue Richter Scale 90th Anniversary Silver Coins available here come with presentation boxes that include a Certificate of Authenticity. The boxes arrive with a Richter Scale-themed shipper. The reverse side features colorized visual elements, while both sides feature proof visuals.

On the obverse of 2025 Proof Colorized Niue Richter Scale 90th Anniversary Silver Coins, you will find a portrait of King Charles III. His Majesty is shown in left-profile relief without a crown on his head. This effigy of His Majesty was created by Jody Clark.

The reverse side of the 2025 1 oz Proof Colorized Richter Scale 90th Anniversary Silver Coin features a design with cracked earth and the pulses of a Richter Scale reading. Today, the Richter Scale’s legacy persists in popular culture and media reporting, where “Richter Scale” is often used as shorthand for any earthquake magnitude measurement, despite most contemporary readings actually referring to moment magnitude.
