The Richter Scale, introduced by seismologist Charles F. Richter in 1935, changed how earthquakes are measured by offering a clear way to rate their size. This new commemorative releases on behalf of Niue mark 90 years since that breakthrough. Today, 2025 1 oz Proof Colorized Niue Richter Scale 90th Anniversary Silver Coins are available at BullionMax.

Working at the California Institute of Technology, Richter built a logarithmic scale where each whole-number step equals a tenfold jump in measured amplitude and roughly 32 times more energy. Early on, the scale was tuned to Southern California quakes and the seismographs used there, which made it especially handy for comparing events in that region.

All 2025 1 oz Proof Colorized Niue Richter Scale 90th Anniversary Silver Coins offered here arrive in presentation boxes with a Certificate of Authenticity. The outer shipper carries a Richter Scale theme. You’ll see colorized elements on the reverse, while both sides display proof-quality visuals with sharp contrasts.

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 appears in left-profile relief without a crown. This effigy of the King was created by Jody Clark.

The reverse side of the 2025 1 oz Proof Colorized Richter Scale 90th Anniversary Silver Coin shows cracked ground alongside the pulses of a Richter-style reading. Though scientists now use moment magnitude for most measurements, “Richter Scale” remains common in everyday language and media as a shorthand for earthquake strength.
