Update on the imminent next chapter; On other forums, I have received nothing but positive feedback about this coin from respected members whose judgment I value. In fact, to date, not a single person has challenged it. Across these platforms, potentially thousands of people have seen the coin by now, and no one has come forward with an alternative technical explanation to my theory—or even attempted to do so. Ultimately, individual opinions do not matter at this stage; the coin is now out of my hands. The entire matter is being approached objectively from both a historical and a scientific perspective.

In the last 24 days there was only a single post other than this thread in this section of the forum, imo this thread counts as numismatic research and all the information is relevant to the subject.

looks like someone was trying to make an undated one .......

Thank you for your help

Rare ? No chance there was about 60 million made

The problem is the banks no longer take them for exchange, so if impaired in any way, their value has actually reduced to the scrap cupro-nickel price. As with many commemoratives, they were hoarded, so there is no point in getting a worn one if you want it in decent grade. If I can get £3 for a really nice one, I'm happy. Most go in the rummage bin, or the big smelter in the sky.

Technically yes, but nothing out the ordinary. If a die is filled with grease (because they are stored that way before use to stop oxidation), then it won't compress when striking coins leading to weak or missing detail. This happens frequently as they use a lot of dies. If the flan is slightly thinner at one point, then it likely means it has been cut from the edge of a sheet, which depending on the amount of metal left for the last sheet say in the batch, could simply run out of metal to use. The sheets for making flans will be squeezed between 2 rollers to get the right thickness, which eventually must result in insufficient metal to fill the gap. It has curiosity value for many, but is a feature that's regularly seen. Someone might pay you a pound or two for it plus postage. For added zeros, put it on ebay and say the decimal point wasn't struck up. I'm sure someone will fall for it.

Hi sorry does that mean it’s a mint error

found in my change today 2025 by the way

Hiya - thanks guys. Rare in the sense that they are no longer in circulation and therefore not legal tender. I know many were made at the time though. yeah when I filtered eBay to items that had actually sold, it seems they don’t go for more than £3-£10 unfortunately. oh well….

Or to put it another way. Face value + (£1/ebay price).

It will either be the dies blocked with grease, or more likely given the weakness to both sides, a weak strike or a non-uniform/standard thickness flan. Weight?

If mint 'error' or just worn? I think it's probably been weakly struck with the result that some detail is not properly formed.

They aren't rare. I have no idea what crazy nonsense is on eBay for them, I suspect it's people asking silly prices, money laundering, the usual rubbish (but not actually genuine sales).

Hiya Could anyone give me any info on this rare 1973 50pence hands coin? I have been trying to get a legitimate value on it but am getting very varied results on eBay etc. Any ideas? In decent condition but not sure how to grade it properly? Many thanks 🙏🏻 ☺️

like wise, I will go off for a look see 👍

Just wondering if anyone can help trying to figure out of mint report or just worm

A pound, and better spent than hoarded given its condition. I assume it is genuine and not a copy?

Plenty, but I don't want to take over the thread and quite a few are shown elsewhere. I have approx 2 dozen in the collection with different reasons for the various errors as made.

Awesome faults , great to see these 👍 any others ?

Is this coin worth anything?

Hi Shelly. Sorry, but no large value. It is a result of a die beginning to break up shortly before it dies. Given enough time, every die would show this feature (or something else related to the wear process) as it is due to a chip breaking off, which leaves a depression in the die surface where it shouldn't be and results in a raised lump. You might get something on ebay for it, but don't plan for a night out on the proceeds! List it for more than the cost of a second class letter stamp plus 5p and you will have a profit, as there is a collector for everything. In numismatic terms it is called a cud. FYI, another die fault arising from their destruction includes cracking prior to complete failure (leaving a raised irregular line or lines). The pictures help to explain what I mean. The second also shows a depression in the reverse field due to the flan having a fault too - usually due to bad metal mixing or a trapped air pocket. Raised will be on the die and recessed (incuse) due to the flan. Faults have many varieties and can make an interesting collection in their own right. If you are interested and want to pursue something along these lines, ask questions and search through past threads. It is fun (honestly). Edited to add that the weakness in REX on the obverse is likely due to the compromised integrity of the reverse die, as the die axis is inverted and so follows the line of the reverse flaw. Weak or missing letters is another error rabbit hole to look into.

I Nearly scrapped this one for being a ex mount ...on the reverse some rather nice initials have been sympathetically added circa 1887
