NGC certification 2722096-001. This coin was offered as a regular 1831 Proof Crown on both these previous occasions, the obverse die with the flaw indicates that some 1831 dated Crowns were probably struck later c.1834 perhaps to accompany examples of the 1834 dated Proofs for a special order. The Latin legends translates on obverse as "William IV by the Grace of God, King of the Britons, Defender of the Faith," and on the reverse "In the year 1831."
