Hello everyone wanted to share my latest mint error with you!! It's a 1979 P Susan B Antony $. I can't decide if it's a die adjustment strike or struck through. Lets see. and i think it's a near date. What is it?
That is struck through grease, not an adjustment strike. On the topic of adjustment strikes, @mikediamond wrote a very interesting piece arguing that most of the so-called adjustment strikes are not actually. See here: https://www.coinworld.com/news/us-c...tment-strike-remains-a-persistent-pe.all.html To tell the difference, take a look at NGC's page on the subject: https://www.ngccoin.com/news/article/1115/ What you would expect from a die adjustment strike, or from one of the errors Mike describes, is that the high points would be weakest. The pressure is not set properly, and so the high points (which are the lowest points of the die), will not have the pressure to fully strike up the coin. What you see are that the fields and lettering around the rim are the parts missing detail, and the centers are fully struck. The fields and rim are the highest parts of the die. Grease on the die is going to produce an effect like that.
Very cool pickup! Definitely a strike through. Lots of things can explain a lack of detail. You have strike throughs, die adjustments, worn dies, thin planchets, split planchets, wrong metal, wrong planchet, wrong stock, and then just plain ol' weak strikes, in addition to circulation wear and damage. Notice how similar yours looks like to this quarter struck on dime metal. At first, it appears to be a strike through, and even has the same wear around close to the rim. This one below is a weak strike, which could be a die adjustment strike. And a thin planchet (2.2 grams instead of 3.11)
