    Attend ANY event at which U.S. Mint personnel are present. They really are dumb as a bag of hammers, both management and front line staffers. They are some of the most clueless people you’ll ever encounter in numismatics. They. Understand. Nothing. This includes Directors, and Acting Directors of the Mint just as much, if not more so, than any other level of staff.

    Don't let @VKurtB fool you.  Pennsylvania drivers leave a lot to be desired.  They need to go to Alaska and get a course in Winter driving.  Two inches of snow and the highways are cleged with wrecks.  My sister, a born and bred Pennsylvanian, is the worst driver I've ever seen.  I wish she would convert to being Amish and drive a horse and buggy  but then we'd probably end up with horse steaks for supper!

    At least it could be worse. You could be in Alabama. These folks can’t drive worth a lick, stone cold sober. The auto insurance rates here prove it. Almost double what they were in Pennsylvania. The utterly insane highway designs contribute. We’ve got a Mazda/Toyota joint venture going in here, and the rumor is that the car’s software goes into “God mode” when you say, “Hey Siri, hold m’beer, Imma try sumpin’.”

    I recall your original post and can guarantee that it will come back as "damaged, plated" or something similar. You failed to do any research on the operation of XRF analysis, even after it was said that the X-Ray beam can penetrate up to 100 microns. Having worked with analytical data including XRF, for well over30 years, it was easy to conclude that your data was a result of the combined plating and underlying copper cent.  
    So yes, you made a big mistake and needlessly spent money.  Chalk it up to the price of tuition

    This might be a clearer image of mushy details on a coin. This is the letter "I" in LIBERTY on a modern quarter. Any metal not parallel to the coin's field (table) contributes to reduced contrast and softer-looking details. Notice the irregular top surface of the letter, and the slight rise in the field adjacent to the letter. (Last photo, I promise. I know everyone's bored stiff with this.... )

    @Coinbuf I believe you are correct.  There has come up, here and ATS, an awful lot of those coins found in the latest archaeological dig in the recently closed Walmart parking lots and called 'Error' or 'Variety'.  Their heads are full of that 'I'm gonna get rich' nonsense.

    Here is a more visually oriented approach. (Image profile diagram is exaggerated.)
    At upper left is a relief image of the word LIBERTY on a current quarter. Blue indicates lower and red higher relief relative to one another. The thin red diagonal line shows were a detailed measurement was taken.
    Upper right is a color image showing a selected relief measured range across the L and I, ending just before the letter B.

    At bottom is the measured relief beginning just left of the L and ending just left of the B. The light blue/cyan color line is the profile. Red “Xs” mark relief height measurement points. The greatest point of relief on the letter I is 0.028mm above the field; the greatest relief on the L is 0.023mm above the field. The profile shows that the top of both letters is not flat, but irregular. Further, the letter I has greater relief above the field than the letter L. (Is this due to metal flow or die design?)
    Notice the red angles where each letter intersects the field. The blue/cyan profile clearly shows broad curvature, and the outside angles are in excess of 114 degrees.
    The result of these measurements is to show why modern coins look “mushy.”

    The title is from a post on this thread: https://boards.ngccoin.com/topic/426807-1987-p-dime-possible-error/. It refers to circulation coins from the 1980s.
    A useful answer deserves more than being buried in an obscure spot.
    Several factors go into the visual sharpness of a struck coin. The most commonly noted are the pressure used to strike a coin, and the softness of planchets before striking. Softer planchets mean that metal flows better into recesses of dies and this increases the uniformity of relief height above the fields. Increased striking pressure has a similar result but the metal tends to recrystallize differently than with softer planchets. Visually there is little differences except under high magnification.
    Before changing to clad metal planchets in 1965, the Mint Bureau did extensive testing to determine changes in processes and dies that would improve the durability of equipment. Experimentation continued over several years and one of the more significant findings was that the intersection of relief and the table (field) on a die was a critical stress point and source of metal failure. (This can be seen on Morgan dollars where die cracks often originate and connect these intersections.)
    To reduce this stress concentration and thereby increase die life, the Mint Bureau made two significant changes. The first was to make the relief-to-table intersection less abrupt – that is, to smooth the curve and thereby disperse stress along a greater area. The second involved changing the slope of the sides of relief – especially inscriptions. This is the angle between the top surface of a letter and the junction with the table (field). For coins whose reductions and master dies were made before adoption of the Janvier reducing lathe, this is about 10 degrees. For coins made during the Janvier lathe reduction era the angle increases to about 15-18 degrees. Current coins, such as quarters, have a measured relief slope of about 24 degrees.

    Our eyes perceive sharpness as a function of contrast. Greater contrast produces greater visual detail and a stronger perception of relief. As the side slope of inscriptions increases, more light is scattered from the shallower angle and the total contrast of a letter with the flat field decreases – making the letter look “softer” and “flatter” even if its height above the field is unchanged. Further, smoothing the intersection of relief and table (field) scatters more light, thereby reducing contrast and apparent sharpness. (The reverse of peace dollars 1922-1928 is a notable example of excessive slope.)
    The effects of these, and relief alterations produce coins that are “mushy” or lack the acuity of detail that we see in older coins. During the 1980s some experimental changes were put into production with the result that much of the coinage lacked sharpness and visual clarity.
    Modern die making uses machine tools, and these can change the factors mentioned above. But so far the US Mint refuses to return to more acute angles for low-mintage commemorative and NCLT bullion coins.

    Alex in PA. reacted to Lem E in First time seeing WWII OPA Tokens in hand   
    A friend I work with knows I am into coins and brought in his grandfathers old coin and paper collection for me to look at. The collection is mainly well circulated coins from the 40s and some coins from early 1900s with a few pre 1900 coins. Mostly US coins and a few world coins in the mix. Wheat cents, IHCs, a few Barbers, a Morgan, 2 cent, shield nickel, lots of V nickels, etc. Mostly coins from WWII era. Nothing too extraordinary, but still neat to look at and actually get to hold in my hand. Two things in particular caught my attention. First was the Japanese government Peso currency from the Japanese invasion of the Philippines. I thought Japanese Peso seemed strange, so I did a little research and learned a little about them.  The second were the OPA (Office of Price Administration) Rationing tokens. One blue and one red. I found these the most interesting pieces in the collection. I kind of knew what they were but never really knew much so I did a little more digging on them. Used during WWII along with the stamps for food. Blue for processed foods and red for meats and fats. I haven't had the opportunity to see very many personal collections and don’t really get to see things I don’t collect myself. These things are small (dime size) and very lightweight and a little hard to handle for me. (I dropped both of them at least once) I just thought it was cool to hold those pieces of history in my hands and learn a little more about them. It is one thing to see pictures of things, but quite different when you are actually holding that history. Learning the history is one of the best parts about this hobby. I didn't post the other side because they look the same on both sides. Anyway, just thought I would share that experience. Thanks for looking.

    You have a dinged up 1884-O Morgan dollar that likely will grade as AU, value in that condition is $40 give or take.   If you want to spend $40-$50 to grade a $40 coin that is your choice, I would not.
