This coin weighs 2.3g and is 18.5mm in diameter. As seen in the pictures there are patches of graininess on this coin. I am confused as to wether this is a fouree example of the L. Sempronius Pitio Denarius or if it is an authentic example suffering from internal crystallization. The weight seems too low for it to be a normal non-crystallized authentic coin. It would be great to have some of your thoughts on this issue.
