£1 Coin Minting Error ‘Confirmed’

Rumours of the Dual-Dated £1 Coin appear to have been confirmed in the national press today.

Although we haven’t seen the coin ourselves, we’ve spoken to the collector claiming to be in possession of one and seen a number of images, leading us to believe that he has found a genuine error.

The error in question is a 12-sided £1 coin with two different dates – 2016 on the obverse and 2017 micro engraved on the reverse.

The Dual-Dated £1 feature the dates 2016 on the obverse and 2017 on the reverse

So, what everybody wants to know is, “what is this coin worth?”

At this stage it’s difficult to answer with any certainty. The error is very hard to spot with the naked eye and there is currently no indication as to how many of these error coins have been struck.

Probably the best example to compare it to is the 2008 undated 20p where there was an initial spike in interest and some coins sold for an inflated price in the thousands. However, this did settle down fairly quickly and today you’d expect to pick one of these up for between £50-75.

What is clear, is that this appears to be a genuine error and as such considerably more collectable than many of the mis-strikes and tampered with £1 coins that have recently appeared online.

£1 mis-strikes make headline news

The 12 sided £1 coin has made front page news time and again from members of the public spotting mis-struck £1 coins in their change.

However, it’s important to be aware that these headlines vastly overstate the scale of the problem.

1.5 billion £1 coins were struck – that’s 30 coins a second – for the new £1 release in March 2017, so it is inevitable that some variances have occurred during the striking process, affecting a small number of coins.

But remember, mis-strikes and variances are not the same as genuine errors.

Here are some of the mis-strikes that have been reported so far:

One coin found in Birmingham by Sarah O’Donoghue was thought to have melted in the middle causing the Bi-Metallic part of the coin to bleed into one another. However, this isn’t actually the case and is in fact likely to be because of a ‘bad’ or misaligned blank being used leading to this particular mis-strike.

This particular mis-struck £1 coin, and a few others that have been found recently, are undoubtedly numismatic curiosities. It is certainly possible that these coins will fetch a little more than face value in the near future by interested collectors. However, the minting process is never completely exempt from human error, so it is worth checking your change carefully.

“It is very unlikely that there is a serious problem with the new £1 coins. With the large amount of coins that were struck ready for the launch in 2017, it is inevitable that there will be some variances among a small number of the £1 coins. With the coins causing excitement in the press and more people than ever checking their change, these mis-strikes are cropping up more than usual.” – Ian Glen (Change Checker Managing Director)

The ‘polo’ pound

There have also been reports of new £1’s missing the middle section of the coin BUT collectors should beware.

As a word of warning to those wanting to get hold of one of these coins, don’t be fooled into spending more than you need to.

It is relatively easy to prize the two parts of metal apart by freezing the coin and using a chisel to knock the middle section out.

Ultimately these mis-strikes are unlikely to make anyone rich, but they are undoubtedly very interesting and would make an exciting addition to any coin collection.
