When the civil war broke out in England in 1642 the mint at shrewsbury was removed to the New Inn Hall at Oxford, where gold pieces, consisting of triple Unites, Unites, and double Crowns, were struck.

All of these coins have on one side a portrait of King Charles I, and bear on the other a scroll with the words Religio Protestans, Leges Angliae, Libertas Parliamenti (abbreviated), referring to the King's declaration, on September 19, 1642, that he would "preserve the Protestant religion, the known laws of the land, and the just privileges and freedom of Parliament." The type upon which this inscription occurs is, therefore, called the "Declaration Type."

The other inscription, Exurgat Deus dissipentur inimici , is from Psalms (lxviii. 1).
