UK 2021 Insulin Silver Proof 50p

Joining the likes of Stephen Hawking, Rosalind Franklin, John Logie Baird, Charles Babbage, the Royal Mint have just released a new Silver Proof 50p coin which sure to capture the attention of collectors.

Each of these previous scientific themed coins have been snapped up by collectors upon their release. And this new UK coin, marking 100 years since the discovery of insulin, is set to go the same way. 

Struck from .925 Silver to a Proof finish

The Royal Mint have struck each 50p from .925 Silver to a Proof finish, with each blank individually struck several times to create the perfect, flawless 'Proof' finish. And it's this superior quality that makes Proof coins so sought-after amongst serious collectors.
