2014 Great Britain £2 Silver Britannia, 1 oz .999 fine silver — the celebrated “Lunar Horse Mule.” On this error issue the Royal Mint struck the obverse using the Lunar Year of the Horse die, producing the wide toothed-rim border that does not match the standard Britannia obverse. NGC attributes the variety on the label. Obverse: Queen Elizabeth II (mule die). Reverse: Britannia standing with trident and olive branch. Graded NGC MS69 PL (Prooflike). NGC cert 3861677-228.
