Posting these for an antique dealer friend. Looks like two Republican and one Imperial, in a silver brooch which is likely Victorian? Please help with attribution/authentication/values, and share any other info you find relevant. Sorry we can't see the edges. Thanks.
They all look like cast fakes to me and not any sort of replicas I'd expect to carry any value outside of the metal they're made of.
The one on the right looked cast to me, but I wasn't sure if it actually was, or just merely porous. They looked "off" to me at first glance, but not enough to condemn them outright.
