It took me a while to find the reason why this coin looks the way it does. What is your opinion? Queen Christina of Sweden 1 Solidus, 1/48th Thaler. Date is 164X
Well since no one seems to have an answer, I guess I will give you a hint. https://auctions.stacksbowers.com/l...060-rarity-5-copper-plain-edge-control-code-1
It is a clipped planchet. While that’s an error that’s worth a bit of premium on more modern, uniform machine-made coinage, it is quite common on coins of this era (which were struck on roller dies), and therefore it is not worth any premium. But it is interesting.
Some of you may not know that the US mint and GM set out in the mid 60's to produce a roller press in which GM said that they could build a press that made 10,000 cents a minute. Check out this article: https://usrarecoininvestments.com/coin_articles/gm_roller_press_cent.htm
I don't think that these were made from actual planchets @lordmarcovan . So, I wouldn't call it a clipped planchet. I believe that they were pressed on a strip of metal that was fed thru a set of wheels. Like this link below. https://www.landisstudios.net/product-page/roller-milled-coinage
Excellent point. You are of course correct about the strip. And you found a photo of such a strip. I searched for one in vain.
