A coin will get warmer when struck by a hammer just like a nail will. The energy of the hammer blow is converted into heat. The atoms and molecules in the coin will be compressed a great deal by the hammer blow, and this will break metallic crystal bonds in the metal matrix. This creates heat. The energy of the hammer blow must be conserved, and heat is a large part of the equation.

Friction is caused between the hammer and coin. The heat generated by friction gets transferred to coin and the coin gets warmer.
