Anyone Is Good At Grading Roman Ancients (Constanine).

And if they make a grade I'm unsure of.thanks for any information or grading.

Roman coins cannot be graded like modern coins. You cannot just assign a single number and expect it to be meaningful.

That being said, the first one is well-centred with all the inscriptions legible, and in terms of wear I might say VF

Obverse: CONSTANS PF AVG
Reverse: GLORIA EXERCITVS

So a coin of Constans, 337-350 CE

The mint is Siscia. B is the Officina , SIS is the mint. I can't see it well enough to narrow down the particular variety.

I cannot read the inscriptions on the second coin, but it is definitely quite a bit more worn than the first.

The Roman economy was imploding during this time period, suffering from inflation. The coins were constantly shrinking, and new larger denominations were being issued which also varied in size, shrinking over time.

The denominations of these coins are still poorly understood, as the Romans themselves left no surviving records as to what each denomination was called, or even what the nominal face values were supposed to be. They are often just lumped together as "late Roman bronzes".

But as a general rule, if you have two coins of the exact same design and mintmark, but one is noticeably larger and heavier than the other (accounting for things like corrosion and damage), then you can assume that the heavier coin is probably older.

I'm also going to move this thread to the Ancients forum.
