No expert here, but it looks to me like Machine Doubling (MD), caused by a slight bounce in the die as it strikes. Interesting, but common and with no added value.
Well, I am a glutton for punishment, and dumber than a bag of hammers, so naturally, I had to post it. Thanks for the input. The damage on the obverse is from a coin-roller, correct?
Machine, Mechanical or strike doubling. It's all worthless doubling. Sorry. Cool coin for educational purposes. Coin rolling machine. You are correct.
Thank you, Sal. I'm in reviewing the various examples of doubling. Honestly had no idea that flaws in the minting process were so ubiquitous, so numerous, so varied. I thought they just pounded out millions and millions of flawless coins, and any variation from a clean result was highly irregular. Nope. Still find it fascinating.
You are welcome. Here is a good site for reading when you have time. Wexler's Coins and Die Varieties (doubleddie.com)
The Mint actually does pound out millions of flawless coins, along with the millions of stinkers. The real problem is that there are a myriad of ways that coins are damaged before and after they reach our grubby little hands…imo…Spark
For someone like me, having just taken an interest, it's profoundly complicated. Stuff I find fascinating is so commonplace it hurts. The extent of the knowledge of the people on this board is beyond impressive. I have way too many questions. Need to do some serious reading and find some videos on the minting process.
Getting your bubble burst does hurt, and the majority of the members here have had it done too. So, now that you have jumped in with both feet you have joined us in the deep end of the pool. Welcome. Go to: doubleddie.com ( Wexler ) and read all the sections, especially “How dies are made” , “The Minting Process” and “Worthless Doubling”. You will launch yourself lightyears into the future in this hobby. Remember it is a hobby and have fun!…imo…Spark
That happens when the planchets move when they’re struck. Takes a little study to differentiate from a doubled die. This website has the explanations you’ll need: https://doubleddie.com/. Just take it in nice and slow, you’ll start getting it.
The planchet moves in the collar. Think of the psi. That's why these collars can't hold them. Now don't get all bent out of shape, it doesn't take much.
