The oldest coin, the 1877 20c. was minted at Paris, it has mint marks A, with anchor and bee. the 1894 50c. coin has the same design engraved by Albert Désiré Barre, but that year was minted at Santiago Chile, and the mintmarks removed. In this time, Uruguay coinage was aligned with the Latin monetary union.
The 1916-17 50c coins were minted at Buenos Aires. I have not learned of the engraver. My 1916 example is pretty far gone, but it is a scarce date, so I am glad to have it.
finally the 1930 20 cent coin was the Pierre Turin design for the centennial, minted in Paris, with the cornucopia and torch mintmarks exactly as on the French 10 and 20 franc coins of the era. In addition to Turin's seated liberty design, Morlon also provided a beautiful Jaguar and rising sun design for the 1930 centennial 10c. coin in bronze, minted a Wien, Österreich.
Uruguay also had small denomination coins minted at Heaton's of Birmingham with H mintmark in 1869.
Later small coins were minted at Wien in 1901, and at Poissy in 1924, among other places! so a very interesting little country from a Numismatic perspective.
