Carlo Ludovico di Borbone — better known as Charles II of Parma — ruled Lucca under the terms of the 1815 Vienna settlement, which awarded the duchy to his mother Maria Luisa as a life interest before he formally succeeded her. The arrangement was always temporary: the Congress had pre-agreed that Lucca would revert to Tuscany upon the Bourbon succession to Parma, which is exactly what happened in 1847, ending the independent coinage series entirely.
The KM#34a designation distinguishes this from the earlier 34 striking; the CNI XI attribution places it within the broader northern Italian corpus compiled by the Corpus Nummorum Italicorum under royal patronage between 1910 and 1943.
