UK 2017 Isaac Newton Base Metal Proof 50p

A pioneer of the ‘scientific revolution’, Sir Isaac Newton and his theories completely changed the way we understand the world.

To commemorate the scientific genius, in 2017 The Royal Mint released a 50p coin. And now you have the opportunity to own this impressive design struck to a Proof finish standard – the ultimate collector’s finish.

The SOLD OUT Isaac Newton series

The Isaac Newton 50p series issued in 2017 is highly sought-after by collectors – that’s because the complete series has long been sold-out at the Mint…

Isaac Newton Brilliant Uncirculated 50p SOLD OUT

Isaac Newton Silver Proof 50p SOLD OUT

Isaac Newton Silver Piedfort 50p SOLD OUT

Isaac Newton Gold Proof 50p SOLD OUT

However, we have a limited number of this extremely sought after Royal Mint back-issue coin as a Base Metal Proof.

The Proof finish is usually reserved for precious metal coins, however today you have the rare opportunity to own the Sir Isaac Newton 50p base metal with the ultimate collector’s Proof finish.

Limited numbers available

However, these Proof versions are far rarer than the Brilliant Uncirculated coins, and we only have a limited number available for Westminster collectors.

This 50p Proof is unavailable at The Royal Mint and given the fact this coin is rarely available to own individually as a Proof base metal coin, demand is likely to far outstrip supply.

Add to your basket today to secure one for your collection before it’s too late.
