Sovereign of Thirty Shillings: Edward VI Enthroned (obverse); Shield of Royal Arms on Rose (reverse)

This extremely rare coin was struck at the Tower mint during the last period of the reign (1550–53). It was struck in high quality gold of 23 carat 3 1/2 grains, and the mint mark, an ostrich head, is unusual and unknown outside this coinage. The mint mark can be see on the obverse, above Edward's crown and before the text starts.
