 New Zealand 100 dollar polymer banknote 
 Reserve Bank of New Zealand
On July 10, 1967, New Zealand decimalized its money away from the British system (which Great Britain would abandon in 1971).  The  New Zealand dollar  (nz dollar)  was then introduced to replace the New Zealand Pound, at an exchange rate of two dollars per pound.  In 1992, a new series of New Zealand banknotes was introduced where the portraits of Queen Elizabeth II were replaced (except on the 20-dollar note) by portraits of prominent New Zealand personalities.  Ernest Rutherford was chosen for the highest denomination  (100 dollars).  Since 1999, the New Zealand paper currency has been replaced by  polymer banknotes  featuring similar designs and colors.  The above picture shows the new version of the Rutherford 100-dollar note.
 Arms of the chief of 
 the clan Rutherford

The British physicist Ernest Rutherford was born in New Zealand, 20 km to the Soutwest of the city of  Nelson.  Raised to the  peerage  in 1931, he became Ernest Lord Rutherford, first Baron Rutherford of Nelson  (Ern, for short).  The "arched" curves dividing the field of his shield are meant to be exponential curves  (a reference to the decay of radioactive nuclei which is also featured on the above banknote honoring Rutherford)  whereas the "martlets Sable" and the "inescutcheons voided Gules" are clearly from the arms of the chief of the Scottish  Rutherford clan :

Rutherford Argent, an orle gules, and in chief three martlets sable  [beaked of the second].
D'argent, l'orle de gueules, accompagnée. de trois martinets de sable, rangés en chef.  (Rietstap)

A famous quote attributed to Ernest Rurherford:   "All science is either physics or stamp collecting."
Well, he  was  a physicist but he got the  Nobel prize  in  chemistry...   That taught him a lesson!  Coat-of-arms of Ernest Rutherford  Signature of Ernest Rutherford DigPlanet   |   Wikipedia   |   Quantum Theory
