    Just follow these instructions and I will show you the error...

    Take a look at the first image...
    Note: When I first saw this image I assumed my coin was the same as the #2 coin because of the color. Then I noticed that each variation of the coin had a different weight, so, I weighed my coin. It weighs exactly 2 grams. The second image is a picture of the coin on the scale. THEN I NOTICED IT. In the first image. The only difference in the obverse sides of coins 1 and 2, that I can see, are the devices on either side of the 5's. My coins design matches coin #2 in the image, but it only weighs 2 grams.

    What I think happened is, somehow, a Copper-aluminium planchet from the #1 coins process got mixed in with the Copper-aluminium-nickel planchets in the #2 coins process.

    Tell me what you guys think? Also, If it is a planchet error, what might this coin be worth?

    Just me being silly and stating the obvious, I guess, but aren't all Piefort/Piedfort coins usually double the thickness with the same diameter and therefore, weigh twice as much as the normal coin? Applies to ALL GB Piedfort issues. Is your coin a Piefort/Piedfort issue?

    Yes. The design matches #2 in the first image above.

    Standard issue was 17 mm dia. and 1.3 mm thickness.

    What does all that mean? I am still a novice at this. Thanks.

    Sorry I didn’t realise that or make myself clearer. There is a normal circulation issue of a coin and then there is a special issue usually very limited numbers for collectors either struck on a highly polished flan/blank/planchette called a ‘proof coin’. To further complicate things, the Piefort in French and Piedfort in English version are coins that display the same denomination and have the same diameter as the regular circulation issue but they are twice as thick and therefore, they weigh twice as much.

    I think your coin is the standard issue coin produced in many millions for general circulation. Whereas the coin you are comparing it to is a Piefort example. It says so in the photo you have posted. That is why your coin is half the weight of the Piefort coin.

    As an example you can do a search on the Great Britain 2017 sovereign and the 2017 Piedfort sovereign and you will see what I mean. The latter is twice as thick and therefore twice as heavy.

    In short, I don’t think your coin is an error coin. Hope that helps.

    Oldhoopster It seemed like a good idea at the time.

    Your coin is the normal Copper-Nickel composition that has toned slightly over time

    Your coin is a normal circulation coin. The privy marks changed their orientation in 1975, when the owl was replaced by a dolphin. That's why the Numista images are different. As 1934 Wreath Crown said, a piedfort would be twice the thickness of a regular coin.

    Examples from my collection:
