I found this in some loose change I got from the grocery store today. It looks really clear to me that's it's a DDR. What you all think I hope the picture are good enough it's the best I can get with what I am working with. The coin itself is not the best of shape but it is what it is.
Recessed lettering around the whole perimeter…AKA incuse, as properly identified by @Pickin and Grinin . Also correct: doubling on the incuse lettering produced by a worn die, properly identified by @Collecting Nut . Worn dies routinely produce coins with die deterioration because they are overused…imo…Spark
Quality control does monitor it. They eventually pull the worn die and replace it with a new one. It just sometimes takes time. They use several dies for the millions of coins struck.
The mission of the US Mint is to manufacture coins that are recognizable as US legal tender. They are intended to be used as trade with an unaided eye as guide to their position in the monetary system. The intend was not to make every coin match the design perfectly. If you want that you should buy proof coins. Whenever you magnify the coins you go beyond the mission of the design and manufacture process. Your coins still meet the design acceptance criteria IMO.
The longer the mint can use a die the less it costs to manufacture coins. As long as it’s up to standards for public use it’s fine with the mint.
All recent coin dies are made using single-press hubbing (for quarters since 1997 I believe), so traditional doubled dies no longer occur. But even so, all the perceived doubling on this coin radiates towards the rim. If it was actual die doubling with such a large offset, as you proceed around the coin the devices would be wildly offset north or south and not towards the rim, right? The hub doesn't change diameters.
You know, I hate to say it, I sound like a broken record, I know, but just look at all these pictures. Why doesn't it occur to read, first, then look, that's what I don't get. Here, this is what you're seeing, there: https://doubleddie.com/144843.html. Nice pictures of it.
