The definition given above is, of course, suitable for the American coinage series, but other mints have "branches" as well. The Canadian mint has two branches, Ottawa and Winnipeg, though for the most part they don't have separate mintmarks. Historically, the British
Royal Mint has had several branches throughout the world, including Australia, Canada, India and South Africa.
Please note that just because a country has several different mints within it does not necessarily make them "branch mints". In Australia, for example, we have two mints, in Canberra and Perth, but they are completely separate organizations. The five mints in Germany are owned by five of the German state governments, rather than the Federal government, so are likewise considered separate mints rather than "branches" of the same mint.

Wikipedia article says much the same thing.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
