Bullion sales charted updated, along with a couple of comparison graphs

Just a quick heads up that I’ve updated all the bullion sales charts from the Perth and United States mints, right up until the end of April 2022. These have been behind of late, so I’ve rectified that, and also added a couple of comparative graphs showing total annual sales of the pair since 2013. Those latter ones can also be downloaded as an image, although how helpful that is remains to be seen.
