This looks like a ragged clip. I should think any numismatic term including "hole" (blowhole) should apply to a coin with a hole in it. Seriously, please educate me as I'm not an error coin expert.
There is no way of proving that the coin you post was made by or had anything too do with a ragged perforation (blowhole). It would be better to label it as a ragged fissure type error. JMO. https://www.error-ref.com/fissures_-_ragged___smooth/ https://www.error-ref.com/ragged-perforations/
I posted one yesterday, similar but the last number in the date is missing. I called it a ragged clip because that’s what the dealer I bought it from called it. @paddyman98 called it what I said in the title. I believe he is correct. To me it looks like a blowhole, just so near the rim it broke through the rim.
@paddyman98 stated that ragged clips are from the end of the roll and included this diagram. If memory serves me correct this was discussed on CT a few months ago.
I get it - this is an April Fool's joke. One coin has a HOLE through it. One coin does not. A hole pierces something. If I scrape my knee and leave ripped up skin, I don't have a hole in my knee. My knee has a ragged, damaged, incomplete surface. Yesterday's example is missing metal (a hole) completely surrounded by the rest of the coin.
Nice thought but I didn’t even think about it April First. Honestly, I can’t see a lot of difference in these two coins. I would think a ragged incomplete planchet would cover more roughness on the rim area. (As in the example I posted that Paddy posted yesterday.)
I'm sorry. I cannot make it any clearer. One more thing though. A clip is mad by a sharp round tool. it's edges are NOT ragged.
I don't understand how the upset mill could handle the coin without leaving signs. Did the piece fall off after the rim was upset?
I’m still having difficulty in understanding and communication from my high BP. It’s better but not like it was. It’ll just take time.
