Is this a new £1 minting ‘error’?!

Last year we reported on the ‘Dual-dated £1 coin error’ where the dates on the obverse and reverse were different, one reading 2016 and the other 2017.

Now another £1 coin ‘error’ has been discovered and this one is very interesting indeed! It would appear that a 12-sided £1 coin die has been struck on an old round £1 coin blank.

In the past week alone, we’ve seen 3 examples of this ‘error’ coin.

The first was from a Change Checker from Burnham-on-Sea who told us that they’d listed the coin on eBay. After receiving 22 bids, the coin sold for £205!

Another coin is being sold at an auction in London on Wednesday 21st February. The auctioneers, ‘Timeline’, who are based in Berkeley Square, describe the coin as an “exceptional modern rarity” and go on to say “…the coin is sure to attract much attention when it crosses the block later this year”.

The third report we have received was this morning from another Change Checker. Our advice to anybody who believes they have found this coin, or any other ‘error’ coins, would be to send the coin off to The Royal Mint Museum who offer a free verification service.

They will send the coin back to you with confirmation of their findings, which can take a few weeks depending on demand for the service. Here is the address:

Dr Kevin Clancy, Director of the Museum, The Royal Mint Museum, Llantrisant, Pontyclun, CF72 8YT

As yet, we have not seen proof that these coins have been verified by The Mint, so whilst they look genuine we will keep an open mind for the time being.

As usual, if you think you have found one of these coins or any other interesting ‘errors’, we’d love to hear from you.

    I have a Charles dickens with the writting on the edge upside down like I read in the express. Is there any other details I need to look for to authenticate it is a mint error? It is 2012

      Hi Chalky, This is actually a common misconception. The outer writing is applied at a different time to the two faces, therefore it’s pot luck which way around the writing will be. Thanks Luke

    Hi.
    I have a £2 Charles Darwin coin where the inner ring is the reverse way round. So the faces of darwin and chimp are on the side where the queen should be and vice versa the queen on the side where Darwin should be. Guess this is a rare mule?

      Hi Steph, this certainly sounds interesting. If possible, could you email a couple of photos to info@changechecker.org and we’d be happy to take a look at this for you. Thanks Luke

        I’ve already done that. Thanks

    • Luke Hearn on February 6, 2018 at 1:51 pm

      Hi Laura, I would suggest having a look on eBay at ‘recently sold’ items, that way you should get an accurate value for your coins. Thanks Luke

    I have a new £10.00 note with the first letters being AA and numbers 11 is this worth anything?

  7. Declan on February 2, 2018 at 1:16 pm

    Hi, I have a 2, 12 sided one pound coins. With the date 2016 on them.
    I also have 2, 12 sided one pound coins with the dates 2017 on the both of them.
    They all look the same only for the dates.
    Are they wort anything?

    • Luke Hearn on February 2, 2018 at 2:01 pm

      Hi Declan, these would be worth face value, they have different dates as they were struck in different years. Thanks Luke

    Good morning.
    I have a few 12-sided one pound coins, where the 1/£ hologram doesn’t appear to be clear. Is this a printing error or just my eyes?
    Any advice welcome.
    Many thanks!

    Rebecca

    • Luke Hearn on February 2, 2018 at 8:05 am

      Hi Rebecca, obviously i haven’t seen the coins but this would sound like a slight mis-strike rather than an ‘error’. Thanks Luke
