In 1841 Queen Victoria sovereign is coming to auction next month armed with a £20,000-30,000 estimate.
The "young head" gold coin, which looks to the left is "virtually as struck" and an "exceptional specimen", according to the auction house. Examples in such condition are extremely rare.
It is a great time to be investing in coins. The GB200 Coin Index recently found that the leading 200 British coins are up 13.3% pa on average since 2002.
The coin, which last changed hands in Boston, US in the 1960s, will form the centrepiece of an Ancient, Islamic, British and World Coins and Medals auction in London on July 3-4.
The sale will also feature several coins from the Seaver Collection. American Jim Seaver, who died in 2011, amassed some 5,000 ancient coins during his lifetime, with a particular emphasis on Roman specimens.
The remainder of the collection will appear later in the year.
Among the leading Roman coins to go up for auction is a Maximian Hercules aureus from AD 286-305.
Valued at £6,000-8,000, it features Jupiter seated holding Victory and a sceptre, and is believed to be an unpublished specimen.
Although it features some scuffing to the edge and minor marks, it is said to be otherwise "virtually as struck".
For Greek collectors, a Heiron II (275-215 BC) from Syracuse, Sicily will also feature, with a £10,000-15,000 valuation. The king of Syracuse features proudly on the obverse, while on the reverse Nike drives a chariot. The extremely rare coin is in good-very fine condition.
