If shown as a trio, these figures represent the three metals used for coinage. This personification rarely was used on coins. Patientia no photo yet 'Patience' holds a scepter and was very rarely used on coins. While the type is listed in literature, I have not seen an example. I denarius 'Peace' holds a branch and scepter.
Some coins show a branch with cornucopia or cadeuceus.
Pietas Lucilla denarius 'Dutifulness' sacrifices over an altar from a patera. Providentia Septimius Severus denarius 'Forethought' points at a globe on the ground with a baton. She often holds a staff. Pudicitia Julia Domna denarius 'Modesty' is veiled and makes a gesture with her hand on her breast. Some coins show her pulling away the veil.
