I have a rare book, "A Numismatic History of the Birmingham mint" it shows photo's of all the coins made by Heatons mint for countries all over the world., Iran, Iraq, Saudi Arabia, India, Mombasa, China, European, African and South American countries, the list goes on to cover just about everywhere.
There are details of how many coins were actually struck, where they were sent etc. Sometimes the mint supplied just the dies and blanks, sometimes the machinery to mint them together with operatives from the mint to teach them how to set up the machinery etc. A fascinating book if you collect coins. They were contracted to supply an entire mint to Burma, 1864 the Birmingham mint received a contract from the government of Burma to supply a complete mint including buildings, 1200 dies, minting equipment and start up supervision to train the locals to run it. The mint reached the royal capital Mandalay in February 1865 and it was up and running on 11th November 1865
