Hey all, I found a coin today that is upset a few degrees and was hoping someone could shed some light on it.
Im assuming when a dye is fabricated that it would have grooves in the sides(assuming its round) so when it gets fitted into a press the installer wouldn't have to worry about aligning the dye, or maybe a certain shape so it can only fit 1 way.
My question is, with the massive amount force that it would takes to create a coin, do the dyes end up getting twisted in the housing or is it just human error?

Never could figure out why they call it a "Upset Die"
as opposed to Rotated Die, but anyway it is caused in
the minting process. To put it simply, the Hammer Die becomes loose
and with each strike, causes the die (NA spelling) to slightly rotate.
Unless the rotation is 45o or more, there is not much added value.

From the older meaning of "upset", being "knocked over"; as in the old slang expression "to upset the apple cart".

So, logically, an "upset die" would be one with between 90 and 270 degrees of rotation, so that one side appears "knocked over" (upside-down) compared to normal.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

I think these days the dies probably have something to keep them straight (a pin-hole maybe?) but I don't know how long that has been the case.
I think that's a recent thing though and that in the early 20th century alignment was probably by eye.
