The text indicates specific problems faced by the
Christian communities identified by St. John. Since this is practically the only source of these communities in the late 1st century, there is little way to verify them. Since St. John rebukes the inhabitants of
Laodicea on Lycus for the lack of fervent faith and focusing on worldly goods, it must be assumed that this was the case.
The whole region was rich and prosperous, so it's hard to find any special marks on Laodicean coins. Most of them are bronzes that do not stand out with anything special from coins minted in other cities of the region. You can view them here:

Asia are the cytophoric tetradrachms of
Hadrian - we can note here that
Laodicea is one of the five cities for which the most were produced (the four others are
Ephesus,
Smyrna,
Sardis and
Hierapolis, not mentioned in the Apocalypse).
