About Stephen Hawking 2019 50p Coin Gift Pack

An uncirculated 50 pence coin commemorating the late physicist Stephen Hawking, who passed away in 2018 at the age of 76. Written above his name on the coin is the Bekenstein-Hawking formula, which describes black-hole entropy, and shows that the surface area of a black hole expands as it consumes more matter.

Included is a special first day cover featuring the six dynamic stamps from the 100 Years of Relativity issue and a unique postmark for the first day of issue. This cover comes with a filler card with issue text written by Prof. Stephen Hawking, Prof. Malcolm Perry and Sasha Hajnal-Corab. On the back of the envelope there is also a further endorsement from Stephen Hawking.
