Another very rare English coin is the gold British Fifty Shillings which had only been minted once. It is believed to have not entered circulation and was only a coin pattern to test dies. Researches also state that the fifty shillings were minted together with the Broad coins, forerunner of the gold coin Guinea.
The obverse of the fifty-shilling coin features English political leader Oliver Cromwell with the legend that says OLIVAR D G R P ANG SCO HIB &c PRO which means “Oliver, by the grace of God Protector of the Republic of England, Scotland, Ireland, etc”.
On the reverse side is a crowned shield that bears the England Commonwealth arms with the legend PAX QVAERITUR BELLO 1656 that literally means “Peace is sought through war”. The edge of the gold coin has the inscription that means “A protector of the letters, the letters are a garland and a safeguard of the coinage”.
Only eleven specimens of the British Fifty shillings are known to exist that they belong to the list of rarest British coins. The British fifty shilling coin prices may reach about £15,000 to £20,000.
