Has anyone observed any type of trend involving CUD'S? Are they more prevalent during a certain span of time, in a certain denomination or a certain metal? Have they pretty much been eliminated from more modern coinage, or does it still happen with some regularity? I find them fascinating but never find them in the wild!!
Hey Sarge! Hoping that your staying safe and healthy! About your Questions, you bring on some very good ones and I hope someone can answer them fully.
@1stSgt22 Interesting question. I'm not sure about a trend but they can occur on any coin. Here is a website http://cuds-on-coins.com/ This is a book about Cuds One thing I've noticed over the years is that newbies mistakenly state that die break issues such as Cuds, die cracks and die chips are added metal. It's not. It's the same metal from the planchet that flows into the void of the die. There is never added material.
I found the one in my profile when I was 8... Haven't found any since. So yes, they do occur still, the same way die chips and die cracks happen. They are just much more rare because of how a die crack has to form to create a CUD.
I don't believe there is a definitive answer to your question. Why? Because a cud is more about the tempering of the die and over usage, which can happen to any series, any time.
Hey Top…. Just addressing the “finding in the wild” part of your question…… For fifty years I collected old coins and never gave a second thought about errors and varieties until I joined CT…. A while back I decided that the “BIE” Lincoln cent minor error was pretty cool and it seemed fairly common based on what I read here….. Now in my years I have saved many many thousands of wheat cents. When I had my knee replacement, I searched every one of them…. Not one BIE in the bunch…. Just a few months after that I went thru a fast food drive thru and received a brand spanking new and very nice misaligned die dime…… I think that at the rate the US mint bangs these things out, you can’t help but have a few errors slip through. We just have to be in the right place at the right time with good fortune shining down on us I believe.
