In response to your question in the latest E-Sylum concerning Mint reports, I think the following information might be of interest: apart from the reports already mentioned from the U.S., Canada and Great Britain, Mint reports have also been published by France (Paris; 1896 till now, first on an annual basis, later on covering 10 years of activity), Belgium (Brussels; 1900 till the 1920s, in principle on an annual basis, but due to WWI on a more irregular basis later on), the Netherlands (Utrecht; most of the 19th and 20th century on an annual basis), Japan (Osaka; I do not know the frequency) and Italy (Rome; only a few single years before WWI and a report covering 25 years between 1918 and 1943).

The Swiss Government published detailed data on the activities on its Mint (in Bern) on a yearly basis, although not in a separate report, but in a general statistical report on the activities of the Federal Government. I am not aware of Mint reports for Germany, although I suppose, like for Switzerland, that data should be available in more general official statistical publications.

Obviously also the annual reports of most central banks contain information on monetary affairs, including in some cases mintage figures.

And the procès-verbaux of the conferences organised by the Latin Monetary Union between 1865 and 1921 also often contain detailed statistical data. Actually, the reports by the Mint in Paris since 1896 were published in order to comply with the stipulations of the agreement of this monetary union, by which member states were obliged to exchange statistical information on coinage matters; first, this information was exchanged between the ministeries of foreign affairs only, and was not made public, but later on, it was decided to have them published with the help of the French Government, leading, as said, to the publication of the annual reports in 1896.
