An analysis by Alain Eliya and colleagues of coins minted in Sidon in the fifth and fourth centuries BCE reveals a change in their composition over time: while a coin from circa 450 BCE contains about 98% silver and 1% copper, a coin from 367 BCE (the end of Ba’alshillem II’s reign) contains 74.2% silver and 24.7% copper, giving it a relatively yellowish appearance that traders would have noticed.
