I think some have called that "skip" with the die slipping on strike...Something of that sort...Comes with a shelf-like appearance at the date and occasionally other devices.

Indeed, as have I. However, the mint did "flub" on occasion and struck coins on thinner planchets. I bought a bunch of them as a lot from London Coins about 10 years ago. Have a few others and thrown in were some off metal strikes and off center, etc.

Would need to see a picture. An awful lot of so called "thin flan" 20thC coinage is post mint damage/tampering as the coins have been submerged in acid either deliberately or else in acidic soil conditions before being discovered as detector finds. I myself have unearthed many such pieces. The giveaway signs are that the surfaces are mottled, stippled or porous where the acid has eaten away constituent parts of the metal alloy. If the surfaces are anything different from a normal circulation piece, then I would fear that is what you have...

I'll have to check as he has it back. I think its a little thinner still.

Interesting. I had never come across other thin flan 3ds. I have a very thin 1944 3d. The normal 3d is 2.69-2.72mm with a vernier caliper. The thin 3d is 2.14-2.16mm.How thin is the 1956?

Another coin collector had a Looking at this, the verdict........ "it looks like an Edward IV 1st Reign groat of the Light Coinage issue (1464-70). No marks at neck, mint mark crown on the obverse. London mint." 🎉 Happy Happy Happy!!!!

Hi there, my friend asked me to check out his 1956 3d coin that has a really thin flan. I looked this up but could only find the thin flan 3d from Gurnsey from 1956. His coin is not the Guernsey one but looks like the normal 1956 3d brass coin but with a thin flan. Anyone seen this coin before? Maybe I didn't search hard enough But all I could find reference to was the Gurnsey variety. Thanks in advance for any information. DrP

It's always good to learn. We all do, albeit mostly through mistakes, not having gone to the effort of preparing ourselves adequately for the items in question. It is always helpful to acquire a few higher grade items in your areas of interest as well as being cleanly and clearly struck. If correctly identified, then you can use those as a reference for the various design features you need to check to drill down into the sub-type. Don't be afraid of spending decent money on a good coin. It doesn't suddenly become a 50p lucky dip item worth nothing just because you paid more than you normally would.

Thank you for update.

I sent an email to the developers and they said there were many issues with Invision forums and listed a whole range of the causes - one of them was the rich text issue which you fixed, but there were several others some of which were very technical and beyond my understanding! However, they did suggest trying another browser, so I went back to my Chromium browser for predec (I also use it for banking as it doesn't involve the very irritating 2FA thing where you have to get a 6 digit code on your phone).

The last time I looked the earlier coins with the same error were about £5-£10 I think. Perhaps someone will pay a little more for a very new one, in case there aren't as many like that as usual (which I doubt, it seems to happen a lot on the new shape £1 coins).

Hi, I wondered if anyone had any example of single digit date repairs for the 1961 - 67 Pennies for example a repair only on the 9 or 6 ? I seem to be only finding doubling. Just starting 1967 and have two different examples. Both reverses of which have slightly doubling on Britannia on the wrist of the hand holding the trident and the lower arm of the hand holding the shield. Best Regards

Just curious if anyone is interested. In a 2025 £1 could with error. Is there any value to it?

Isn't it nice that we have someone on here with some nice inherited coins lol

Hah, I honestly didn’t mind, Chris…gave me my biggest smile of the day so far. 😆

Michael Gouby was selling the Type 4 and 5 1992s for about £60 in EF. So I guess somewhere between £30 and £50 would be reasonable. I think the 2006 is rarer than either of those. I've got about 20 type 4s and maybe a dozen type 5 - not EF condition you understand. They are much more common though.

I should have said 'hard to find' because yeah, if money is no object it would be easy to amass hundreds of them. I did used to include a double-page spread on the 10p varieties but it never really took off. In the next book I will clarify and perhaps even add values for at least the 2006 type A. If you're offering £30 for an 'as-new' example then that's its value and I think perfectly fair and realistic.

I have found a Kew Gardens 50p in the past. I believe I would have found more, but obviously everyone was looking for them and removing them. No one - other than myself - has been actively looking for these 2006 ten pences. I have four. Three I've found, one AU/possibly UNC from eBay earlier this year. I know Tony Clayton has at least obe, possibly two of these. I did hear of someone else who had one. So that's what seven known coins for certain. I suspect perhaps only one die was used for these and I just happened to acquire two of them close together in 2006/7. I haven't seen one since until this morning, and I have been looking! There's nothing rare about the Kew Gardens 50p. I could find countless on eBay or elsewhere and buy a mint state one tomorrow, for a price obviously, but they're are readily available, expensive doesn't equal rare! I hope you can update your coin book with these varieties!

I love this kind of thing. Modern rarities that no one is bothered about because there is little financial incentive to look, they involve a little effort to understand and spot and because they haven't been exposed in the Sun or on dodgy click-bait tabloid websites. I hate that side of decimal collecting, plus all of the deliberate misleading crap and even fakes on eBay over the years.... remember the dateless mule 20p, when people were actually grinding off the date of normal ones and attempting to pass them off as 'dateless'! How many 2006 10p's do you think you've actually seen in total? 2006 was a massive mintage at 118m+, so it would seem the type A die(s) were for whatever reason, just used for a tiny fraction of that total. Even if it was for a million coins, it's still under 1% of the 2006 total. All these years later and finding a stunning example will be very hard (as you know!), like finding a decent 1807 slave trade £2 with no DG initials (i.e. the circ only variant). They may well be rarer than the Kew 50p. Might even be comparable with the mule 2016 £1 coin with the tiny 2017 dates on the reverse - and surely more of those should exist in the wild but a magnifying glass is needed to even see it.

Wow, that's great to find out, thank you, I did have to read up on Mule meaning I have read before and so this is a Error coin A mule coin is a type of error coin that features a combination of designs from two different coins, typically due to a mistake during minting. Wow.. this is very interesting to also learn. many thanks for all the time taken, its going to be an interesting few weeks as these still need to be worked through.....

You're magically an enthusiast now. The expert grader old rank was always there. No idea why they need to have 2 now.

Eighteen years and I've found my third one in change today. Not a great looker though.
