[QUOTE="usmc60, post: 2910427, member: 76739"]Kurt I had the honor of going through the Denver mint on my way to Seattle back in 89. A friend of mine and myself as we went into Denver he wanted to go to the Harley shop. So I went to the Denver mint for their tour. Their commercial production line was very impressive, the presses actually reminded me of machine-gun fire. All they needed to do was turn out the lights put some tracer coins in there and we'd have one light show. Now it is my understanding the planchette goes over the reeding die. Then it is struck by the hammer die pushing it down into the reeding collar, at this time any excess material is pushed to the top towards the die. Assuming everything lined up correctly. Sometimes this material could be either thick, or extremely thin. I have found due to the temperature of the coin, if this material pushed up is extremely thin it can actually fold over on its own since the metal is very pliable. Then you will create a rim burr strikethrough. As indicated by the photo. As I've said before, there are a variety of burrs. Just like they are a variety fins. No it seems I have to bring this up again. At least we have some good members on this talk forum, have the common courtesy not to make fun of someone that has a learning problem. Dyslexia. I cannot spell. I rely on voice recognition to communicate. And a comment always made well you have spellcheck. Think about that remark how spellcheck gonna help if someone does not know how to spell. Believe me I do my best and I tried to double check everything. One thing I will give CT credit for it's making me learn a lot more by having to do a lot of research. USMC60[/QUOTE]
