I looked on variety Vista for this quarter and they didn't have it. Where else can I find state quarter errors? Or is this indeed an error? on the reverse look at Theodore Roosevelt. Especially the R's. And are those radial lines from die deterioration? The front looks the same. I'm suspecting the whole coin might be die deterioration. Thanks again
those radial lines are flow lines from heavy die deterioration, such as below The smashing metals gets flowed around, and over times etches the die facing.
Current dies are made using the single squeeze method also known as class IX doubling. Some of the characteristics are different and learning them sounds like something that will help you. I think the incused letters make ID more confusing and most of what you see is still DDD and MD. IMO, you may want to go back to Wexlers site and spend some time reading about it. Most of the Class IX doubling is insignificant IMO, but there are some that are considered desirable, and may be worth searching. Plus if you become proficient at it, there is a possibility of finding new DDs as coins are issued. Hope this helps. There used to be a couple members on here that played in this sandbox and were pretty good at it. Haven't seen them in a while, though https://www.doubleddie.com/58222.html and other tabs
