The consequent cross-border financial speculation caused by the discrepancy in coinage values was threatening economic stability.
The exchange rate was set at 24 livres = 1 pound, making the 2 sous coin equal to a British penny.
The last coins and notes of the livre currency system were issued in France in the Year II of the Republic (1794).
In 1840, a new copper coinage was introduced for Jersey, based on a penny worth 1⁄13 of a shilling in sterling coin, the equivalent of 2 sous.
On 7 February 1923 the States passed a law to ban the import of foreign copper coinage in sums exceeding 20 sous.
