Trying Make Cents , On Strikes With Grease

To everyone that has insight on this topic, I'd really like to know if anyone has ever field tested the idea that grease will impede 88,000 lbs of pressure on a surface area less than 1/2"x 1/2". If it's nothing more than a term that's universally used but not actually understand to be the cause of the specific distortion, I could live with that.

What drives me nuts is the fact that anyone with the aspiration can get a Doctorate in Numismatics which in my mind must hold some scientific and forensic training. Simply put, grease must obey the laws of thermodynamics. Pressure translates into heat, heat changes the properties of grease, probably just burning it up at that pressure. I think some explanations are misleading and in this case ridiculous.

I don't have a degree in metallurgy nor numismatics. I do have experience with large punches, presses and a variety of metal alloys. I've never seen grease do anything other than it's intended purpose, lubricate a friction point. If the struck thru grease theory had any weight to it your wheels wouldn't turn well, engine wouldn't fire correctly, it would even make it difficult to open and close doors because it would impede the surface it was supposed to lubricate.

I'd love to know the history of the attribution in general. My personal theory is someone was presented with a coin that has been restruck/overstruck that would cause lots of distorted lines and basically look like what grease might do if it were a solid material.

I believe that missing letters, worn areas on coins are generally the cause of build up on the die of copper/zinc/silver/nickel or whatever alloy the planchette is made of. Another possibility is die wear or slight misalignment.

The only way this will ever be answered is to actually test the theories. Grease would not even be on my long list of possibilities.

Thank you.

Thanks for replying, To be frank I understand there are mostly individuals that are just learning and it's rare something legitimate comes along. I'm not a pro, I've spent the last 2-1/2 years studying memorial pennies and a bit of time on Jefferson Nickels. 70-80hrs a week. I've made a ton of mistakes, I can't grade to save my life but I do know the guidelines for DD vs MD. Thanks mostly to the advice of knowledgeable individuals on this site and the common reading sources.
What makes me upset is when there is to much objectivity, rules are used and broken at will, nothing is black and white. I've been advised several times that a DD will exhibit split corners or serifs. MD can't do that. This coin clearly has seperate doubled devices on the eye, nose, mouth & west neckline.
I believe the due that struck this coin was nearing the end of life or had been in contact with the hub to create several impressions either due press malfunction or operator mistake. When it was hubbed properly, the outside was cleaned up along with some areas in on the neck and hair. I believe the detail is too small to file the eye. That's the most logical chain of events I can come up with.
I can see the details in the pics just f fine. They may need to be enlarged. I'll work on getting some better shots. Thank You.

I've added some pictures that clearly indicate the separation of points/details. Definitely not MD. I marked a few points of tripling for ease of identification. If I'm wrong in my assessment please explain why and how it differs fundamentally from the 1943 Double Eye Nickel or 1916 Nickel (Specifically Mouth/Neckline). I'd rather learn than just be agrivated at the irrational objectivity. Thank You All.

I came across this coin today. I know there are very few Double Die quarters over the last 40 years. I find definate doubling on the Eye, Mouth, & Thought line to the East. There may be extra thickness to other devices but I don't have the experience or knowledge to speak to that aspect. I'm not sure it's visible in the pics but I think there are 3 different Eyes to the East making it a TDO. The livr isn't as prevalent but visible through a loupe. Thanks for the insight. I'm excited about this one.

Dearborn, I generally agree with your assessment. I do have a few pics of 1970 S that are hard to identify. I'll be as detailed as possible as to what I'm seeing. I'll post them shortly.

Slightly related, has the US mint ever commonly re-used working dies? Is it possible for a working die to be re-hubbed and used for multiple runs? I can't find specific info on this. Current info suggest a penny die will strike 1 million coins.Even at that # over 5000+ pairs just for pennies.

I'm familiar with the process I've read and watched everything I can find.

The answer to this question will determine my next topic. Thank you all.

1922-D Lincoln Cent Error

I'm no expert, I've studied thousands upon thousands of pennies and I have seen this strike style, (for lack of a better word). Just saw one that was on a 1924 1. What I can add is the fact the US was minting coins for multiple nations as well as Panama, Argentina around that time. In the late teens to early 20's I believe they we were quite active in supplying either planchets or finished coins to multiple countries. The US struck coins for at least 20 countries in 1942-45 or so. Most of the planchettes we're the same weight or at least had 1 identical measurement to the standard US penny. I have a fairly detailed spreadsheet with all the info if anyone's interested.

Long story short....The THICK rim 22D could be a blank ment for a coin 1mm larger or something. When it was up-set the extra material was pushed inwords. On the few I've run across the strike is never even. Roughly 30 of a given side is weak. Educated guess. I tend to think the simplest answer is usually correct. I.E. No one went to the trouble to make a fake that spot on to screw up the rim. I'd think they'd be everywhere as well. Who makes a handful or just 1.

Just an educated guess from an uneducated guy. Good luck. You have the best working this out for you. Definitely lucky in that respect.

I think this is all you are asking for.
Again, I know if several examples of rather obvious discrepancies. I don't go looking for them. I come across them when I'm studying a specific variety and use the great pictures as a resource to become as familiar with the pick-up points and small details as possible.

To be clear, My intent was based out of frustration not malice. I'm a very analytical/logic based thinker and it becomes nearly unbearable when it seems that rules are based on interpretation or subjectivity.

Again, Thank You all for the support and vast knowledge base.

Sorry to do this. That coin is actually from reputable grading company certified as 1970 S SD FS-1401 BN AU-58.If you'd like to look for yourselves then simply search those parameters. My motive is 2-fold, Mostly I feel much more sane than I have over the last year. I'd simply like to point out the subjectivity where there should be as little as possible.

Everyone makes mistakes and I completely understand things like this will come up. I've found several improperly certified coins. I've let it go until today because most of the others I've found are minor and most wouldn't notice unless really looking hard. This was to flagrant to not ask an opinion.

That said, I appreciate everyone's input and knowledge in the forum and will be the first to say that some of the best insight is found amomgst the members.

Thank You All

Thank you all for looking and any insight. I'd just quickly like to know your opinion on this coin if it's a small date or large date. I believe it's a large date but please let me know if I'm wrong. I understand all the identifiers but I'm a little confused about this one. Thank you.

Thank you for your advice on the pictures. I've struggled for a very long time with my Samsung phone and have always gotten extremely high definition overexposed images that absolutely do not represent the coin. I will try with a different device because this is truly a great double die and probably one of the best I've seen on a Roosevelt dime.
***On another note, there are a few images that clearly depict the split serifs. One image of "RTY" clearly depicts the split serifs. One of the images of the day is also pretty good. There is some die abrasion and I can see how that may make it difficult to differentiate between the doubling and the ghosting of a reworked die. Thank you for your insane patient better pics to come. I'm confident this could be one of the best Roosevelt doubles there are.

Just wanted to post this DDO Dime I found. I don't usually check anything other than Pennies because that's all I really know we'll. I apologize for not specifying the doubling type. I think it's CW Rotation from about K8 + E-NE lateral shift. I did the best I could with the pics. The date is my favorite part, the 8 looks like 2 ropes coiled on top of each other. If I've missed something please let me know.
Thanks All

Hopefully, there's an easy rule to follow for this year. I have read everything I can and I understand the difference between LG & SM. I'm running into issues when I find a coin that has a high 7 but the 0 is doubled or extended to the North slightly. Is this always a LD? Is the date fundamentally different like 1960 SM/LG. Maybe I'm getting caught up in the weeds on this one. Again, I get the difference. Is there a basic rule of thumb that always applies? Thank You

*I just noticed the small date is shorter on the tail of the 9 and 7. Possibly all digits. Also seems a bit wider than LD. Is this accurate?

Here are some rim pics. Hopefully they will provide the needed information. I agree with BadThad, definitely been heated. In my opinion it was simply a super hot die. I believe it would show uneven heat marks if done by torch or other implement because the heat would be very uneven. Either way doesn't really matter. Fun coin, looks good. What more do I need? Thank you all again.

To be clear, I didn't ask for a grade out of ignorance. I understand anything that occurs during the minting process shouldn't affect the grade and I wasn't sure if this was too far off the standard to be considered problem free, is it considered error? It's one of my favorite coins. So a grade would be great if appropriate. (Problem free)
I'm confident it's original. I know where it originated from and I'm confident it's been stored since 1943. I've also worked around metal most of my life and I believe it is most likely the cause of a die being extremely hot, changing the properties of the plate. Just an educated guess.

This coin drives me nuts. There are pictures of certified graded versions on very reputable sites that still show partial devices. I'm confident it's nothing more than die polishing or filing that has removed the initials. It is a variety, however I find that a lot of seasoned collector's don't pay much attention to it with the understanding it's just an abraided die. My opinion anyway...

I think you've got it, I'm no pro but I've looked for 1 for a long time and have the points memorized. Always good to double check across all 3 sites. Wexlers, Variety Vista & Copper Coins.

Really just curious about this penny. It's obviously a plating issue, I think I've heard it referred to as gas bubbles but not sure. It's looks great to me despite the bubbles. Just an FYI, I originally thought it was covered in a foreign substance. I assure you it is NOT. There a few spots on the obverse where the bubbles have broken away showing the raw steel core. I'm really just interested in opinion, no serious plans unless otherwise advised. Thank You All.

"Machine Doubling will always make the devices smaller." True doubling will have split serifs & make the devices bigger. I don't know how true this rule is. I find discrepancies all over the place in the world of numismatics. Even on the websites of the big authentication companies I've found coins in the image library of authenticated coins with mint marks completely in the wrong spot for the specific die. Looks like MD to me as well. At least on Liberty. Keep looking, I promise just when you're least expecting it, you'll find something great.
