That was the same century that the native Iberian town Arse (Sagunto, later Roman Saguntum) began minting its own coinage. Before the Second Punic War you see rare instances of Iberian towns minting their own civic coins while using Greek and Phoenician ones for currency along with barter items. Greek coins from Emporion minted in the 5th century BC were found in a hoard at the Iberian walled town of Puig de la Nau along with many other items of silver and gold.
However, there was an explosion of coin usage during the Second Punic War, with both pro-Roman and pro-Carthaginian coin minting by Iberian cities. Not only do we find Iberian language legends in Iberian scripts throughout early Hispania Citerior, but even Celtiberian ones in the Celtiberian script following the war. This continued throughout the period of gradual Roman expansion in the Iberian peninsula throughout the Republic and reign of Augustus, but ceased after that point due to the establishment of permanent Imperial mints.
If you recall, the earliest examples of Paleohispanic scripts date to the 5th century BC, but from what I know the Iberian language legends on coins did not appear until the 3rd century BC (but there might be a very early Sagunto example I'm forgetting). That means native Iberians were using their own scripts as far back as the Classical period but were still using Greek and Carthaginian currency in the Greek and Punic languages, respectively. It's possible that the idea of using an alphabet came about with the earliest exchange of goods using such coinages, but it appears they didn't seem confident enough to mint their own varieties in their own Iberian language until the Hellenistic era.
