Many British people know that one of the rarest coins in existence is the much-famed Kew Gardens 50p.
With only 210,000 coins minted in 2009, these coins can sell for over £150 and as such the majority have been withdrawn from circulation and into the hands of collectors.
However, there is a lesser known, rarer Kew Gardens 50p – and one is currently being sold by the Royal Mint in a live online auction of 343 coins.
Only 629 gold-proof versions of the Kew Gardens 50p coin have been purchased by the public – and the version up for auction has already attracted £4,000 bids. The Mint estimates the proceeds will be between £5,000 and £6,000.
Under the hammer: A gold proof version of the 50p Kew Gardens coin, one of the most sought-after coins, is expected to fetch £6,000 at auction
There is also a one-kilo Queen’s Beasts gold coin, which could fetch as much as £90,000, which is expected to be the most expensive lot.
The auction will feature coins submitted by the public that have been authenticated and valued by the Mint’s team of numismatic experts.
Bidding is possible until December 3 the auction takes place online on the Royal Mint’s website.
Occasionally there are seller fees, but this happens on a case-by-case basis, the Royal Mint says. Here are some of the rarest and most valuable coins up for grabs at auction.
2009 Kew Gardens 50p gold proof
The Kew Gardens 50p is one of the most coveted coins due to its scarcity in circulation and as a commemorative coin.
It ranks number one in Change Checker’s 50p scarcity index. But this gold version is expected to fetch between £5,000 and £6,000.
To show how quickly the value of these gold proof coins has grown, one sold at a similar auction five years ago for £800.
The obverse features a design by Christopher Le Brun in honor of the Royal Botanical Gardena, depicting the pagoda at Kew with a decorative vine winding in and around the tower and with the years ‘1759’ and 2002′ on either side of the word ‘Kew’. ‘.
This coin was first released in 2009 to celebrate 250 years of the iconic West London landmark. It is sold at auction in its original issue box.
Only 210,000 of the circulating 50p were released into circulation and some are known to sell for between £150 and £200.
The 50p was then re-released in a second batch in 2019. These are less valuable but still sell for £80.
A total of 1,000 Kew Garden gold proof 50p coins were minted in 2009 – and only 629 were picked up by the public.

Queen’s Beasts one kilo gold proof
The Queen’s Beasts coin pays tribute to Queen Elizabeth II and features the 10 beasts side by side in one design.
The design was inspired by the ten stone statues that lined the Queen’s route to Westminster Abbey during her coronation in 1953.
