Does anyone have info on this George V coronation medal? Thank you

One side has the royal cypher for George V and it says "In commemoration of the coronation of King George V"

The other side says "Ascension May 9th 1910, Crowned June 1911 and has a woman with a trident and a shield with what I am assuming is the king and queen inside.

Approx 34mm diameter and 3mm thick with a hole punched through it.

Please let me know if you need further info, I couldn't find another one anywhere so don't know where to start. Thanks!
