Sovereign 2014 S.SC7A struck on the day 22nd July, Prince George First Birthday, the error mule, the obverse a currency strike, the reverse frosted and resembling a Proof striking, BU/FDC in the black Royal Mint box of issue with certificate number 106 and booklet. Interestingly on inspection of the accompanying certificate, the Specifications refer to a Brilliant Uncirculated coin, the facing page then 'avoid handling the coin as fingerprints will spoil its proof quality' so perhaps the accompanying certificate could also be classed as an error mule (!). The Standard Catalogue states that only 398 were minted.

Estimate: GBP 400 - 500
