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.

It’s time to really start examining your change again.

Change Checker has just been able to confirm that a small number of “Inverted Effigy” £2 Coins have entered circulation.

The Inverted Effigy Coin has the Queen’s head rotated clockwise by approximately 150 degrees

First discovered by a Change Checker, and now confirmed as genuine by The Royal Mint, this unusual strike appears on a handful of the 2015 Britannia £2 Coins.

The Royal Mint has accounted for the seemingly impossible misalignment of the Queen’s effigy as almost certainly the result of one of the dies working loose and rotating during the striking process”.

The result is that the Queen’s head is offset by around 150 degrees compared to the Britannia design on the reverse of the coin.

Just how rare is the Inverted Effigy £2 Britannia?

The Royal Mint is unable to give any indication of how many Inverted Effigy coins have entered circulation but we can make some initial estimates.

britannia-two-pound-errorThe first-year 2015 £2 Britannia is already one of the most-scarce circulating £2 coins ever issued with just 650,000 coins passing through banks and cash centres.  That already places it third equal in the all-time low mintage charts.

We have analysed 5,000 circulation coins and our results suggest that the Inverted Effigy may have affected as few as 1 in 200 of the coins struck – in other words around just 3,250 coins.

Of course, if the Inverted Effigy is a consequence of the die slipping during the striking process, it is possible that there may be other variations where the Queen’s head is less or more misaligned as the die has worked its way out of position.

Errors, mis-strikes and myths

Of course, given the many million coins The Royal Mint strike each year, it is to their immense credit that mis-strikes and errors are so few and far between.  But, of course, when they do arise, they cause great collector excitement, as some of these other examples pay testament to.

But there are a few myths out there too – upside down edge lettering, the “Pemember” Gunpowder Plot £2 coin and the “Necklace” £2 coin, which all have perfectly normal explanations.

Buyers beware

But finally a note of caution.  I’m sure in time we’ll see some “examples” of the Inverted Effigy £2 for sale online.  Before you think of buying one, please beware.  Are you seeing a genuine Inverted Effigy or just a coin that someone has rotated in a photograph to make it look inverted?
