The new 12-sided piece only came into circulation last month, with manufacturer The Royal Mint branding it "forgery proof" and the world's most secure coin.

But one Brit, who has not been named, says he has stamped out claims that the new £1 coin is near-impossible to copy.

Brow-raising pictures show the apparently-fake coin having subtle but significant differences to the real thing.

The charity worker, from Addlestone, Surrey, described the discovery as "worrying".

It is heavier, the Queen's head is further to the left, the edge is more rounded, it doesn't have a hologram and there is no detail on the head of the thistle.

The new coin is meant to feature a hologram at the bottom which shows a £ symbol and the number one depending on the light.

He said: "If I've just found one, how many are there in circulation already? It's quite worrying. It's supposed to be the impossible coin."

The Royal Mint, which initially declined to comment on reports of the find, now says it is "confident" the coin is not a counterfeit.

An independent coin expert who examined images of the coin for The Telegraph believes these differences are the result of "mis-aligned printing" - the result of a malfunction in thestriking process.

Numismatist Dominic Chorney of coin dealer A.H. Baldwin & Sons, said the clue lay in the fact that multiple elements of the coin are out of alignment.

"The coin appears to be a 'mis-strike', meaning it is a genuine coin which has become mis-aligned during the striking process," he said.

Mr Chorney explained that the complexity of the hologram means the mis-alignment appears to have removed it altogether...
