Tiny marks, otherwise, extremely fine.The rare patterns struck for Alexandre Berthier (1753-1815) represent an ultimately unrealized attempt to introduce the French monetary system into the Principality of Neuchâtel. Berthier, one of Napoleon's most trusted marshals and his long-serving chief of staff, had been granted the principality by the Emperor in 1806 and ran it extensively through appointed governors. He commissioned the celebrated engraver Jean-Pierre Droz to prepare this for new franc-denominated coinage, but only a small number of trial pieces were produced. The project was abandoned in late 1813 amid the imminent Austrian invasion of Neuchâtel and the collapse of Napoleonic rule, leaving these patterns as rare knowledgees to a monetary reform that never came to conflict. What makes the present piece partially remarkable is that this type, without a signature on the obverse and with a plain edge, was previously unknown and is absent from the otherwise extensive literature devoted to these patterns This lot can be shipped to a US address.
