all 100 % real of course !!! national museum !!! top expert, even found by them !! university !! very old royal collections !! even many vases where from Bonaparte !!
There's probably a few that are casts of real coins. Museums do that commonly when a coin is too rare, or being studied, or they are missing a vital sample in their collection.
Being from New York, I HAVE to go to the MET again soon!!! And, Sallent makes a valid observation and point.
The map shows the symbol of the Roman Empire on the territory of the free tribes of the Scythian and Sarmatian ...... but the coins in this museum all copies
