noun
coinage
KOY-nij/ˈkɔɪnɪdʒ/
The making of new coins.
The mint worker uses a hammer and die for coinage.

Etymology
A wedge-shaped stamp gave coin its monetary meaning, and coinage named the money produced or its production. As coining broadened to making or inventing something, coinage also came to mean creating a new word.
In context
New Brunswick was the only colony to strike coinage in silver. So, like we see here, we see a 20 cent piece.
