Depicts the crown of Mary of Modena, and a plan of the walls of the Tower which is split over the four coins in the collection unifying their designs.

The Crown of Mary of Modena is the consort crown made in 1685 for Mary of Modena, Queen of England, Scotland and Ireland, and wife of James VII & II. It was used by future queens consort up until the end of the 18th century.

The crown was part of a collection of three made for Mary of Modena in 1685 by Richard De Beauvoir: a state crown, coronation crown and a diadem (ornamental headdress). The coronation crown no longer exists but the others reside at the Tower of London as part of the Crown Jewels collection in the Jewel House.

A special Tower mint mark features on an official UK coin for the first time (on the left).

A phrase from the poem Human Life of Samuel Rogers (1763–1855):

Went Sidney, Russell, Raleigh, Cranmer, More,
On into twilight within walls of stone,
Then to the place of trial;
