I have several coins I suspect that might be very late roman minimi, all heavily worn, but a few seem to have monograms identical to those of Avitus, Majorian, etc. But these coins are so small, and worn that the legend is unintelligible, and the design unclear. I know that barbaric copies of crisis of the 3rd century coins share the same size, and can be confused for minimi (at least for me), so how do you identify minimi? Is their a good website for it?
