A fine example of the 1839 Una and the Lion five pounds coin of Great Britain has seen the highest bids in Bonhams' June 3 Coins & Medals auction in Los Angeles.

The commemorative coin is one of the most beautiful ever produced in Great Britain and is very rare

The coin, engraved by the legendary 19th century artist William Wyon, sold for $81,900. It was originally part of the 1839 Coronation sets produced to mark the reign of Queen Victoria, and is one of just 300 ever produced.

The coin shows a young bust of the queen aged 20 on the obverse, while the reverse has the queen dressed as Una with a Lion - two long-standing symbols of Great Britain.

Considered one of the most desirable and attractive of all British coinage, this example is particularly fine, free from scuffs and with a minimum amount of hairlines, which are commonly found in this variety.

The 1813 half eagle is one of the easiest dates of its design type to find

Bringing the second highest bids of the auction was a US 1813 $5 coin, which is graded MS64 and sold for $52,650.

The 1813 half eagle is actually one of the easier dates of its design type to find in good condition, though PCGS has graded just three examples at a finer grade than the example at auction.

Also featuring was a proof-63 graded Saint-Gaudens double eagle of 1910, which originates from the Champagne Lanson Bonnet Collection of US Gold $20 Coins that was unearthed in France in 2012.

Selling at $35,100, proof Saint-Gaudens coins are of the highest rarity with a recorded mintage of just 167 pieces, of which just 60-75 are known today.

Paul Fraser Collectibles has a brilliant opportunity for collectors of British coinage - a transitional 1831 William IV proof crown that has an altered obverse die, a variation that has never been recorded before.

This coin provides a superb chance to own a potentially unique piece, which offers great opportunity for additional research.
