Money Expert Alex Cassidy, from GoCompare's Coining It In, said: "As with the current £2 coins, the 2017 £1 coin is bi-metallic, in this case an outer ‘gold’ coloured nickel-brass band with an inner ‘silver’ coloured cupro-nickel disc.
“Because of this, any potential die errors during production, which occurs when the dies have become misaligned, could be worth a lot of money.
The trial coins will not be as obvious as the £5 notes to spot but are already selling online

“Punters should pay attention to both the floral crown on the reverse side for any rotations, as well as the Queen's head, which should sit directly above the new bevelled edge.”
The 12-sided coin is the first major redesign of the pound since it was first introduced more than 30 years ago.

The coin features a raft of new security features designed to prevent counterfeiting, including a hologram-style image on the front and micro-lettering on both sides.
More than 200,000 of the brand new coins were sent out to retailers last year for “testing”.
They were classed as “trial coins” only and are not legitimate tender, however, bidding online appears to start somewhere between £150 and £250.
Alex added: “These new £1 trial coins are fascinating, especially considering the financial precedent of the £2 trial coins in 1994, which have since become one of the most sought after collectable coins in Britain.”
“If these new trial coins turn out to be as valuable as 1994’s, then anyone who gets their hands on them now could be sitting on a future goldmine.”
Many coin enthusiasts will be hoping to complete their collection of all 24 of the old designs, and the Edinburgh £1 dating from 2011 is already achieving £10 to £15 on eBay.

The new coin is the world's most advanced currency
Chards is a leading coin and bullion dealer based in the UK, said: “Bear in mind they are producing over 2.2 billion £1 coins this year.
“We do not think that the 2017 circulation £1 coin will be a good investment – however, the collector coins such as the silver proof, silver proof piedfort and gold proof will be the ones to invest in.”
Some have commented that the new coin looks similar to the Euro
The first batch of new £1 coins will commemorate the achievements of Jane Austen, Sir Isaac Newton and The Royal Flying Corps – all expert pioneers in their fields.
Alex told the Mirror: “2017 is expected to be a good year for collectors, with the trend of 50 pence collectible limited release coins continuing into the new £1 coins.
“That's the main thing to look out for in the near future, because the first run of those collectibles will be huge.”
