The bottom row of the picture has coins with an owl on them - these must be the coins of Athens republic proper. Upper row coins with some faces on them must be of the later period.
To me, it looks like it is only three coins. Upper row is the obverse. Face of Athena, maybe? The lower row is in the same order, showing the reverse, with the Athenian owl, and "A-Th-E" in Greek letters.
What is odd to me is that the two end ones have the reverse image skewed, rather than either 'upside down' (like our Washington quarters*) or the top of both heads facing the same edge.
*Hold a quarter with George rightside up, index finger on the top, and thumb on the bottom, so it can rotate, and turn it around that axis so the the eagle (or state logo) is facing you; it is upside down. If it isn't, check again VERY carefully, then head for a coin dealer, as there are some rare ones that were struck with the reverse 'upside down' so the 'top' of both images is toward the same edge.
