Ancient Ostia presents the largest amount of urban mithraea in the Roman world. Starting from the fundamental corpus published by Giovanni Becatti in 1954, the study of ostian mithraism has now found new life thanks to the discovery of the so-called Mithraeum of colored marbles, from which a research project has originated, aimed at the systematic updating of known, published and unpublished data and the cataloguing of individual monuments, also through new structural surveys, carried out with modern two- and three-dimensional documentation techniques. Here we intend to focus on coin finds in the ostian mithraic context, which, although rather poor, provide useful information for the reconstruction of the life and abandonment phases of these important places of worship.
