On the E OF area it is often weak because the bust formation on the other side. Sometimes affected by a grease struck through issue, because of the widened devices, it is commonly understood for that. But mostly the first issue I mentioned is the cause. So a weak strike, incomplete metal movement during the strike or a lack of metal (light weight planchette issue), or a
Struck Through Grease issues will leave the device looking wider on a normal die strike.
If the devices were thinner, then a heavy die polishing would cause that.
But as mentioned, pretty much a normal coin with non premium issues. But when the right coin comes under your sight, you will know it when you see. Your eye is well trained. Keep looking, it just might be the next coin.
