Hello everyone, brand new to the website. Very excited to get some help as I am new to coin collecting, and there's a lot of things to look for! I think I might have found my first doubled die on a 1989 quarter, but could be wrong. thanks for your help/feedback, Bayelynn
First, welcome to the neighborhood! What is usually referred to as machine doubling is also called mechanical doubling or strike doubling or ejection doubling. It differs from true hub doubling in that it appears to be "flat and shelf-like". This is very common because the hammer die has a tendency to loosen and the continual vibration of the machinery causes it to move back and forth very rapidly, thereby, cutting into one or more of the devices.
Thank you all for your replies! It's great to get some answers, YouTube doesn't know everything . Well, I guess I'll keep looking for a special coin that will be rare n valuable. And I will keep bugging you all Thanks, happy treasure hunting!!
Hello @Bayelynn, What you'll eventually discover is that YouTube has a very limited usefulness. There are many good pieces to review, but tons more to avoid. The best learning comes from dedicated sites than general sites like YouTube. A couple tips when posting photos. Many times, members will find it useful if you post full size images of the obverse and reverse along with your specific area of focus, we probably can offer your more feedback that you might find useful. For instance, the image you posted may show MD, DD, or perhaps both. With an isolated photo it can appear as one thing when it is another. I'm leaning towards DD...or Die Deterioration. Aging dies get messy and the devices show it off. Enjoy the forums and happy hunting!!
