Watch List notes:

† British Coins, George II, proof five guineas, 1731, QUARTO, young laur. head l., rev. crowned shield of arms (S.3663A; W&R.68), certified and graded by PCGS as Proof - Genuine - Altered Surface - Uncirculated Detail, but despite the obvious cleaning (probably long ago) which diminished the mirrored surfaces, this is an important and still attractive gold proof, with an excellent portrait, and only the second proof ever made of this denomination (the first being the 1670 five guineas of Charles II, W&R.48); the presently offered coin is an example of the Royal Mint's early proofing efforts, in this case using the superbly engraved dies by Croker and Tanner; very rare
(80000-100000 GBP)
