Heres a couple coins most wont find interesting, but saw it today n thought it was cool and got it. 2 ancients melted together about 24/25 mm at the longest What little I can see looks maybe like a later follis? but they didnt come trough in the photo.
You quite often see coins like this that have been found in hoards or more extreem from shipwrecks. I recently seen a pile of Roman coins all clumped together that came from a broken jar (Tv documentry) Nice addition to your collection
