Abstract

The composition of a 25-cent Philippine coin is identified by laser-induced breakdown spectroscopy (LIBS). With this technique, the emission peaks of the coin when it was ablated by a 1064 nm (Nd:YAG) laser was shown to correspond to the elements copper and zinc. Traces of iron were also observed.
