Watch List notes:

Great Britain. VIP Proof Crown, 1960. S.4143; ESC-393M (Rarity-4); KM-909. Elizabeth II. Obverse portrait of Queen Elizabeth II ELIZABETH II DEI GRATIA REGINA F: D: FIVE SHILLINGS.' Reverse, cruciform shields of England, Scotland, England and Ireland with emblems, thistle, rose, shamrock, and leek. Crown in center, 19 60 below. The obverse and reverse are identical to both the normal currency issue and the somewhat scarcer polished die variety, but on the VIP specimen the design is frosted and the field highly polished. Superb example. PCGS graded Proof 64 Deep Cameo.
*Linecar and Stone states that a footnote in the 1968 edition of English Silver Coinage points out that the 1960 crown was struck on the occasion of the British Trade Fair in New York and the coins sold at the Exhibition site were struck in the UK from polished dies and exported in special blue plastic cases. After the closing of the Exhibition unsold pieces were shipped back to the UK in bags, having been removed from the cases. In consequence, polished die crowns are very difficult to obtain in perfect state.'
The VIP proofs are considerably rarer than the polished die crowns and ESC rates these as Rarity 4 (11- 20 examples known) The polished die crowns are merely rated as 'Scarce.'. Estimated Value $1,400 - 1,600
