Looks possibly like a woman on the left, a man on the right, and an infant between them. So if that’s the case I expect the coins/medallions depict Mary, Joseph and baby Jesus in a nativity scene.
Or it could the emperor, empress and their child...hard to make out the lettering on the coin.
Yes, one of the medallions is a nativity scene.
I think the other is the baptism of Jesus by John the Baptist.
