The thinner letters example was caused by die abrasion.
I did an overlay of your example photos. The thinner version over a thicker. One photo is an exact overlay and the other is with the photos offset.
As you can see there is no spacing difference, only a difference of thickness cause by die abrasion. John, (yes, another John), I'll start by saying that you taught me as much as anyone else has, a few years ago, on another site, but would have to disagree with the spacing. It would be impossible to "thin" the letters, without creating more space between them. The coin size did not change, the location of the centers of the letters did not change, only the total size of each letter. This being said, the spacing between them, would have to be greater, on the abraded letters. -makecents-

I think that I have done too much layout work for stone and marble in my life and casually used the word spacing without reference. You are absolutely correct that there is more space between the letters,but that is actually the outside edges of the letters. I should have made it clear that the position of each letter in the design , has not changed . In my work I so often use center lines to determine coursing of stone so in this case the spacing of the centers of the letters did not change. Sorta like the Wide and Close AM's . The position/coursing/spacing of the centerlines of the A and M of a Close AM don't change with abrasion , only the perceived space between them. Many thanks for pointing this out !

Different master dies of the same general design?

Hi, thanks for everyone's help! I had some questions on over polished dies and I'd like to try to see if there is anything else to look for to confirm this is reason the reverse on this coin appears this way. I've also included some additional pictures taking a look at the field area that surrounds the devices and the height of the devices. 1. The first 2 images show the E and R in America. There is a noticeable gap between the top of the E and R. This larger gap appears common on the 1978 Proof reverse. Also, when looking at the field area surrounding E and R and the overall height they look normal to me. I do realize it has a tapered look to it but I'm not sure that's from over polishing. 2. I also included an image of U N I that also seems to be of similar height from the surrounding field area. I assume that if a person was using a tool to polish the die it would create devices that maybe are uneven in height? 3. Is the anything else to look for that would help to confirm over polishing changed the appearance of this coin. I also included an image of a proof reverse from PCGS.com. Note the size of the font and the gap between the top of the E and R. Thanks for everyone's help! I'm new to error coins and still learning. The reverse on this coin seemed very different when compared to other late 70's coins. The spacing and gap between the E and R seem very similar to the 1978 proof coin. I do understand that over polishing can make devices thinner, but when looking more closely the height and appearance seems pretty consistent throughout the coin. Another observation with the reverse of this coin is the size of Unites States of America. While it seems thinner the size appears larger then regular strike coins. Thanks again!

This is what I was originally thinking, but, Yeah, I got it now Jon, I wasn't thinking centerline to centerline (which I should have as I do that all the time at work - You see when I hang network cabinets on a TMB (Telephone Mounting Board) I have to measure the mounting holes, but I measure in this case edge to edge - which is the same as center to center.) |

Has anyone ever tried to mount on a wall a power strip that has the mounting holes only on the back? Trying to get 2 blind holes to line up with 2 screws you put on the wall is difficult. So there are 2 ways to get the mounting screws in the exact correct location: 1. put the power strip on a scanner and make a copy of the back of the strip and use it as a template. or 2. if you have no access to a scanner, I measure the hole distance (edge to edge)  Edited by Dearborn

You could use a analog scanner to do it.
A piece of paper and a pencil. Just make a rubbing of the holes for the template!

huh, that could be #3, thanks, didn't think of a rubbing, but then the last time I used a pencil that way was 55 years ago..

Not joking, but there is a pencil behind my ear about 18 hours out of every day. Pencils are extremely handy for many things, but most importantly, mistakes. My reason....

for me, it is a pair of electrical snips, a pen, a small 'tweeker' screwdriver, and a sharpie on my belt

Do you occasionally whip out the sharpy like a gunslinger? -makecents-
