Is there any point in time during production of wheat cent that it is soft, semi liquid, or malleable? I found one coin roll searching that appears to have been handled before it hardened if that is possible.
First, welcome to the neighborhood! I'd like to see photos of your coin before I even attempt to assess what has happened. Chris
Yes, when a coin is struck the immense pressure causes the heat of the planchet to rise to the point where it is temporarily liquid, which is what creates the cartwheel effect on coins.
It does not get that hot. The reason you have flow lines is from the metal being pushed. Flow does not mean liquid. It is the limitations of the English language. If it got this hot, it would anneal the dies.
Thank you for the knowledge! I really appreciate it, that makes a lot of sense. I will use this knowledge in the future! =)
