Machine Doubling is a strike artifact caused by the die "bouncing" slightly at the end of the strike. It can happen at any time, on one single strike or a thousand in a row. As such, MD is not considered a "legit" Mint error but rather an unavoidable occasional consequence, and adds no value. It can strongly resemble hub or die doubling - which is of interest - and is therefore something to become familiar with as your learning progresses.
Thanks for the info and the lack of sarcasm, I already am aware of my lack of knowledge that is why I ask for information from you guys. Have a good one, Mac
People like you - newer collectors thirsty for knowledge - are the whole point of places like this. It's unfortunate that some members don't recognize the value and necessity of developing new collectors for the future of the hobby. Doubly so because numismatics is about preserving history; just preserving the coins isn't enough if there's no new collectors to succeed you. Narrowminded and small.
I enjoy the history of the coins and events that occurred when they were in circulation. Even the commemorative 's though not circulated still remind us of history. I just recently started to look for errors didn't know there were so many types, thanks again, Mac
The others are right, at least about the nose as MD. I think the other at the mouth is an unfortunate "hit" to the coin. Keep looking, you will find a good one eventually. Sadly there are a few here that troll each and every post looking for something they can make a sarcastic remark about. You will never find that in me. But some of us are just trying to be humorous also, so sort us out and have fun. Good pics by the way.
That's not doubling, Mac, it's something else. I'm not ruling out it's strike-related, but I'm not ruling out it was on the die, either. It's just not doubling.
