Your question is imprecise. In your first post, you say "used". Later on it is mostly "issued". Are trials issued? Is a cash coin used as funeral money used? If a coin has a catalogue quote of several hundreds or thousands of dollars, was it used?
You don't mention it, but are you perhaps after the year the national mint was first mechanised? How would you deal with the Maldives, where there never was a mechanised mint? All machine-struck coins were made in another country.
I just tell you what I know. You decide.
