I was kinda under the impression that 80s pennies were the ones to expect this problem with mainly. Is it all types of metals. Or a copper issue? Haven't really ran into many outside of that and then I found this guy *** Moved by Staff to a more appropriate forum. ****** Edited by Staff to Add Year / Mintmark to Title. It's very important to have in the title. *** |

I think it is on the single squeeze die making cents. John1  ( I'm no pro, it's just my humble opinion )
Searched 6.5 +/- Million Cents Since 1971

all dies deteriorate a little with each coin they strike, so how much deterioration is seen on coins is mostly a matter of how long the mint runs the dies
I believe the planchets for nickels are the hardest ones the US mint srrikes into coins, so the 5 cent dies wear the quickest

DDD is starting to show as die wear on the devices in the direction to the closest rim. Note what is not affected? The devices are normal sized. The DDD show on the fields, just like your coin is showing. A doubled die will enlarge/distort the shape on the coin:  Note how these devices are enlarged like an over inflated bicycle tube? That is what to look for. Looking at the fields you will find die wear and Machine Doubling. Look at the centers of the design of the devices.   Examine each example so you eyes will discern what to look for on these doubled dies.

Okay coop. I read most everything I've seen you post on my questions.. my first impression of dd was looking for something like the 55 wheat or 1916 buffalo. But most of what I see on posts and searches is not anything like that. So looking at the center and for more ballooned out, Serifs. So on more worn down (say wash quarters for example) what's the noticeable points to distinguish between flattening and doubling

Take a look at the sites to see what is listed. The directions of the hub doubling. Then, remember these to look on those areas on coins from different mints and years close to those dates. You might find a new listing that way. Flattening that's larger than normal, a pretty much damaged coins. Not much demand for a damaged coin. They become full coins. Move on to the next coin, or set it aside for a second look later. Double Dies a scarce. So don't get bogged down thinking each coin is a doubled die. Otherwise you'll be finding die wear or Machine Doubling a lot. Look for the spread , if not there, move on to the next coin. (Circulation coins probably have been searched many times already. When searching new rolls, your eyes might be the first ones to see those coins. Spend more time on these. If the whole box looks the same. The first 5 rolls would probably tell you what is in the whole box. |

Closer? thicker letters. Some funkiness on edges  |

But most of that is circulation flattening and Machine Doubling on some devices. So this is not a doubled die, but a post strike damaged coin. on a strong DDR on the nickels (1939 DDR) you can see the spread real strong on that coin:  If you coin was this same DDR, then it would be a circulation damaged DDR. What happens in circulation call also alter a doubled die just as well.  Note a closer view of this DDR, you can see notches on the corners of the devices from the miss alignment of the hub during the dies creation. CoopHome: What causes notching on devices? the spread that is not exactly over the premium hub process. thus the corners of devices can show this notching when the alignment of the hub is not correctly over a previous hub process, leaving these notches on the corners of devices.

John1-- I've read that one and a few other versions of big long written out explanations of diff kinds of error. On dd coins and a few other things. And honestly I stop paying attention to what I'm reading without getting through one type. If I have to look up words and end up reading just as much on the definition of a word in the first thing I'm reading. And then go Google an example picture. They are making it way to hard. Lol not trying to be a sick up but I actually like alot of coops stuff. Always got picture examples and not so over extremely technical wordy headache
