Oh, hey what about this I finally got a WiFi microscope so I’m looking at some coins but this is a 2011 P Roosevelt Dime, and I’m looking at YouTube jbcoinsinc and it’s saying it should have a full band but this one on the bottom band it looks like it was struck wrong or not all the way it’s missing the middle line is this a error and could it be worth something
A weak strike will cause bands to be filled in. Wear or circulation will cause the area to look flat. So, to answer your question no it is not an error.
