Royal Mint resume minting their own supplementary tokens. In 1672 the Royal Mint finally took over the production of copper coinage. Prior to the outbreak of the English Civil War, England signed a treaty in 1630 with Spain which ensured a steady supply of silver bullion to the Tower mint. Additional branch mints to aid the one in London were set up including one at Aberystwyth Castle, in Wales. In 1642 parliament seized control of the Tower mint and after Charles I tried to arrest the Five Members he was forced to flee London, establishing at least 16 emergency mints across the
Royal Mint alongside those of other nations until 1858 when London started producing coins for the newly established Canadian dollar. As Canada developed, in 1890 calls were made for a mint to be built in Ottawa to facilitate the country's gold mines. The new mint opened on 2 January 1908 by Lord Grey producing coins for circulation including Ottawa Mint sovereigns. In 1931 under the Statute of Westminster, the mint came under the control on the Government of Canada and subsequently renamed the Royal Canadian Mint.A fifth branch of the Royal Mint was established in Mumbai (Bombay), India on 21 December 1917
