Early coins of gold and silver were minted
from cast blanks using hammer struck dies.
These dies - I read - were made from iron.

How did the ancients manage to produce iron dies
since they did not have the technology to produce
cast iron?
Did they cast a reverse die in bronze which could
then be stamped onto the head of a red hot piece
of iron?
