coin collectors take note.
Thanks BenLurkin and Red Badger.
Note that they got carried there in sacks or chests, but are in mint condition without the wear and tear associated with banging against each other while being bounced on donkey back or unsprung wooden wheeled carts over hundreds of miles of Roman cobblestone roads.
Note that they don't show wear from being used in commerce, being passed from hand to hand, being slid across rough tabletops, being carried in a purse.
Note that the older coins show the emperors wearing spiked headgear (Not worn until the mid 200's)
Caveat emptor
