I would think that right now is the best time to trade coins with the Queen's image as a large number of people are looking at their coin collections and wanting to fill in the holes.

It will be interesting to see how the world reacts to a change from a queen to a king as there are millions of people who've made tearing down "patriarchy" their life's mission.

Replacing images of a queen on coins with a king might make many minds on the left explode.
