Rare Trial Pieces including Kew Gardens 50p to be Auctioned for the First Time Ever!

Have you heard the news that for the first time in its history, The Royal Mint plan to auction rare sample coins for collectors?

Trial pieces are some of the very first samples of a new coin to be struck. They are used to set the standard for each coin issued and are carefully inspected by coin makers to ensure they meet the correct standards before striking of the new design begins.

Trial Coins Put Up For Auction

Rebecca Morgan, director of collector services at the Royal Mint, said: “This month we are delighted to offer a sample of our trial pieces at auction for the first time. Each of the trial pieces has played an integral role in creating the final coin, and offer collectors the chance to own a part of numismatic history.”

The Royal Mint have announced that collectors will have the chance to get their hands on a number of trail pieces at auction on Sunday 26th September.

Included in the auction are the coveted Kew Gardens 50p (the UK’s rarest circulation coin) and the Three Graces (a collection that sold out in 25 minutes last December).

Rare Kew Gardens 50p

2009 Kew Gardens 50p

Considered the ‘holy grail’ of change collecting, the Kew Gardens 50p tops the Change Checker Scarcity Index time and again. In fact, this coin is so sought-after that collectors are willing to pay well over face value to get their hands on one, with our latest eBay Tracker revealing the coin currently selling for £157 on the secondary market!

However, we always urge buyer caution when purchasing a Kew Gardens 50p, as there are a number of fakes out there to be aware of. Find out how you can spot the fake Kew Gardens 50ps here.

1994 Mayflower £2 Trail Piece

1994 Mayflower Trial £2

Rare trial pieces have been seen before, often becoming very sought-after amongst collectors…

In 1994, ahead of the introduction of the UK’s first bi-metallic coin – the £2 – The Royal Mint created a trial piece. This was used by The Royal Mint to test the minting process of the new coin and to help the automatic vending industry re-calibrate their machines in preparation.

The trialled reverse design features a three-masted sailing ship. Although the ship is not named, it is likely to be the Mayflower, which set sail from Plymouth to America to establish the first permanent New-England colony. The outer ring bears the inscription Royal Mint Trial with the date, 1994.

There were just over 4,500 packs of this trial £2 issued and as the coin design was never released into circulation, it has become an incredibly rare example of a bi-metallic £2 coin.

If you own one of these £2 trial pieces you can consider yourself very lucky!

But with the upcoming auction set for the 26th September, we’re sure collectors will be excited at the chance of getting their hands on the trial piece coins offered by The Royal Mint, including that sought-after Kew Gardens 50p which we’re sure will be incredibly popular.
