clashed dies; mint errors in the 19th century

I wasn't around then. How can someone have let a mint press run without planchets?How many hits would the die pair get before a mint worker realise they were ruining them. This obviously happened to many coins. What am I missing here?

    By the mid-1800s, there were presses using pendulums to lift and drop the dies, and other mechanisms to feed planchets automatically... no one had to watch closely... since the technology was still very crude, it was easy for a planchet to not be fed.

  • The mint was experimenting with simple automatic planchet feeders back in the 1790's. And clashed dies are still happening today in the 21st century. In fact with the new presses that strike horizontally it would not surprise me to start seeing an increase in the number of clashed die coins since every time the planchet doesn't seat properly in the collar gravity makes it fall away leaving the potential for a die clash.
