Date on the left one looks 18X# or 13X# (last digit is almost illegible), I think X stands for 10, so 181# or 131#
Date on the right one looks more like 1214, might be 1814. This is what makes hard to spot them, as both dates that could be are in similar periods.
On the Bishop side it clearly writes RAGVSII (From Ragusa). As I said, they look an awful lot like the older Ragusa coin in Numista, but those Omegas where stoppers for me on adding them as that one.
Oh, and both have R mark on Bishop side. Pretty similar to that region coins.
