Forgive my laziness, but you keep telling me to ask questions and I trust your answers far more than my faulty and confusing research. So........., I keep seeing coin after coin after coin (mostly recent cents) with little or no collar. Usually they don't look like the strike is off center, but the collar is goobered. Sometimes one side of the collar (N, S, E, W) is missing, then on the next coin it's the opposite side. Sometimes it's only on the obverse or reverse, sometimes it's both. Sometimes the collar is noticeably fatter, deeper, rounder, or missing entirely but the coin is the same size as one with a full collar. Conversely, I have a 1995 D dime with no collar. It's smaller than other dimes, the planchet is perfectly round and centered, the rim is smoothly cut, and there's no reeding on its edge (please tell me I got some of the terminology right). I know a coin needs to be severiously off center before they become more than a curiosity, and that's fine. I don't think any of the ones I'm looking at show any signs of being struck wrong it's just the collar/edge/rim. There's so much going on with this part of the coin from one to another I would like to understand it better. I'm trying to get better at photos and I could post some that would show what I'm asking, but I'm still struggling getting the lighting correct. Stay safe and healthy, and thanks for any input.
