The standard silver coin of the Roman Republic and early Empire (1st & 2nd centuries AD) was the denarius.
A denarius was a chunky coin measuring about 18 mm across and weighing around 3 grams.
25 denarii made one golden aureus but gold coins were mainly for bankers' use and not normally in circulation.

A copper as was half the value of a dupondius.
The two coins were the same size (about 25 mm) but could be told apart by the different colour
of the metal (brass yellow, copper reddish) and by the radiate crown of the dupondius
compared to the laurel wreath crown of the as.

The small copper coin in the middle is a quadrans, the Widow's Mite of the Bible
and issued regularly up to the reign of Nero but only infrequently after that
