A major diagnostic on identifying varieties is the terminal stage die breaks. These have been a focal point of my collection for many years. As an American ex-pat, I made the choice to transition my focus to coins of Great Britain - essentially start over. American major die breaks are very well documented by Sam Thurman and Arnold Margolis but I have not seen their efforts repeated in any other country. So, if you can't find it, make it! I have been developing britisherrorcoins.co.uk to be this resource. This group has a wealth of knowledge and access to hundreds of thousands of coins. I would love to add your coins to my site. If you have any unlisted major die breaks (cuds) that you can contribute please post them. If it's not already attributed somewhere else, I will give you credit as the discover and I will also give you photo credit. Thank you in advance!

Fantastic! Thank you PWA 1967.

Your second coin is real, just dirty. The micro lettering is very clear on your close-up. It wouldn't be like that on a counterfeit.

Die chatter and double struck are two different things. If a coin is double struck, it has entered the coining chamber a second time or failed to be ejected after the first strike. It would then get struck a second time. Sometimes the second strike is off centre and sometimes it's centred but every time it effects both sides of the coin. Die chatter is now referred to as Machine Doubling Damage in the US error market. Alan Herbert, a giant in US error circles, wrote, "The evidence is very clear that MDD occurs after the strike. The coin design is complete, meaning the die pair has done its job. The bouncing/chattering die moves metal that has already been formed. Struck metal has a different appearance than the metal shoved or moved by the bouncing die. Because of this difference it is possible to trace anything that occurs during the minting process. Anything that happens after the strike cannot be traced as to time or place." MDD is characterised as flat, shelf-like doubling. It is almost always on only one side of the coin and it is almost always the hammer die.

Thank you Mr Bad Example but I've made a decision to exclude tokens.

Thank you very much. It's now posted here - https://www.britisherrorcoins.co.uk/major-die-breaks/pre-decimal/penny How should I credit you?

Thank you, please email me at jrenaud001 at gmail dot com

Thank you Blakeyboy. This is now listed as 1P-1945-1Ra. How would you like me to credit you on the site?

Yes please. Also, do you have a larger picture of this one? Could you tell me the Freeman number of them? And, finally, how would you like me to credit you on the website?

Hi everyone, I've been searching for awhile and I can't find any mention of 1885 half penny varieties. I've looked over Richard Sessions fantastic website but he doesn't mention it either. Freeman only list 354 and 355 which are the circulation strikes and proof strikes. If anyone is compiling an updated resource, I would love to submit this for a listing.

That's great! I love the horizontal shift by the date. You can really see it by how the beads don't line up. Can you please send me a pic of the obverse and a larger picture of the reverse? Thanks! Jason

Now listed as 1P-1861-1a. This would be very exciting if it was proved to be paired with a second reverse! How would you like me to credit you?

What name would you like me to credit you as?

That's an amazing cracked planchet! It is probably just barely held together. It reminds me of the "Broken CC" Morgan dollar - https://minterrornews.com/features-2-4-03-allen_rowe-broken_cc.html It doesn't fit on my site (yet) but it certainly would fit in my collection! Great coin.

Nothing special??? It's a gorgeous example of a retained cud. This is from londoncoins.co.uk, isn't it? I recognise the wear on Queen Victoria's hair and ear. It will be listed as 4p-1840-1Ra. Thank you!

Thanks for this Bronze & Copper Collector. It's now listed as 1/2p-1862-1a. Based on the file name, can I assume that it's F-289? I like to cross reference if I can. Also, can I use your real name on the site?

What a great set! Would you be able to send me a high res picture of your best one please?

Perfect Bernie, do you have a photo of the obverse?

Thank you Rob and Michael, I really should have defined "major die break" and "cuds". I'm really sorry about that. Error-ref.com defines it as "A cud is a die break that involves the rim and at least a little bit of the adjacent field or design. The vast majority of sizable die breaks are cuds. Cuds can assume a wide variety of shapes including ovoid, crescentic, and irregular. Most cuds represent spontaneous brittle failure. A small minority arise as the result of impacts." and a split die as "A split die develops when a rim-to-rim die crack extends deep into the die neck and die shank (shaft). The width of the split is proportional to its depth of penetration. Split dies usually divide the die face into two sub-equal parts. These may be termed “median”, “bisecting”, or “symmetrical” split dies. A width of .5 MM is the determination point which differentiates a rim to rim bisecting die crack from a split die." Unfortunately I'm not listing die chips or die cracks. These are far too numerous and widely not collected for their own merit. This is entirely on me, I will be amending my post so that I am more clear. Thank you both very, very much. -Jason

This much larger picture is more convincing.

I have had the opportunity to go through 33 proof 1998 pennies. Of this group there were: 26 Type 1 reverse C 7 Type 2 reverse C Within the 26 Type 1 there were 8 doubled die obverse. They were all the same doubled die which mostly showed as extra thickness and small notches on "IRB".
