2 Coins - Ancients?

The top one is a replica ancient Jewish coin from the Second Revolt (Bar Kochba) period; see this thread and the link in that thread for some identical replicas. The original coins with this design were silver.

The second coin appears to be genuine; it's from Ptolemaic Egypt, in the name of a "King Ptolemy". Unfortunately, every male Pharaoh of the Ptolemaic dynasty (there were 15 of them) called themselves "Ptolemy", and the eagle was a popular design motif, so I'm not sure the ID can be narrowed down too much further. How big is it?

OK, that does help narrow things down.

The obverse portrait helps, too: I believe it's the rather unusual one of the old king Alexander the Great wearing an "elephant's head head-dress". This was only used on coins of 20-22mm diameter on coins of Ptolemy II and Ptolemy V. On Ptolemy V coins the portrait seems to be smaller, so I would assume this is a Ptolemy II coin, from the "post-reform" series Alexandria mint, dated circa 260 BC. I also notice that the mint control letter between the eagle's legs is epsilon (E), which would make the coin number 451 in the Svoronos catalogue. See the PtolemAE Project web page and compare the types there.
