i have a 2016 S Uncirculated type quarter and I was looking close at the reverse and noticed that the words on the entire lower half of the coin, "ILLINOIS, 2016, E PLURIBUS UNUM" looks very strongly doubled. I'll post a pic of the strongest area and please let me know what you all think. Ball I can find are people finding errors in the immediate picture but this is very strong in the print around the rim. It's easy to see using my 10x loop... Let me know what you guys think. Thanks...
What you see is Machine Doubling. The letters and numbers in this area of all the National Park series quarters are incuse . When Machine Doubling affects them they will expand in size giving a very convincing doubled look.
Thanks. I have really don't know much of the quarters. Lincoln cents.... Now that's a different story!!!!
I've got a 2015 Saratoga quarter exhibiting similar doubling of the incuse letters, but quite pronounced. Not sure what to make of it. I've been reading up on doubling in these forums and have not found a similar issue of machine doubling on a specific letter. Looks like machine doubling occurs over a wider area, and more evenly across that area. This specimen does not make sense to me.
If you want to get an idea what a true doubled die will look like on incuse letters, you might want to search through the listings at VAM World paying particular attention to the word LIBERTY. Chris
Could someone suggest what would be a good video, or other source of information about how the U.S. mint makes its coins so I can know the difference between doubled die and machine doubling? I found this 2016 Jefferson nickel with something going on in the O in Monticello on the reverse. I'm pretty excited I found an error so early in a release without really looking for it, but I'd like to know what I have.
Weavie, Jon Sullivan posted a link on his website here showing how US Quarters are made.. Perhaps this will be what you need
