You need to turn the coin 90 degrees clockwise. I just feel it's a Roman bronze, though I can detect the Greek letter Epsilon behind the head of the sitting person. Good Luck
It looks like a provincial of Nero. Go to www.wildwinds.com, click Roman, click search by Emperor, click Nero, then click to show the list with images. Scroll scroll scroll scroll... after all the Imperial issues are shown the provincials follow. I edited the picture for ease of viewing:
I think it is this: Nero, AE25 of Tyana, Cappadocia. Dated local year 12, AD 66. NERWN KAISAR, laureate head right / TYANEWN ET IB, Tyche sitting right on stool, holding corn-ears, river-god Phoibos swimming right below. RPC 3659; Imhoof FG 466; Paris 750; Lindgren III 954; Falter 684.
What do you believe is different? The obverse appears to be a die match. The OP's coin shows reverse inscription "IB", year 12. The Wildwinds coin's reverse has damage or wear obscuring the date (IB), which is visible on the OP coin. The river god is more clearly seen on the OP coin.
looks like the spacing between upper leg and lower arm is less, and angle of lower leg is more acute.
I agree. But with ancient coins those differences don't carry the same meaning as for modern coins. Each die is handmade; the differences between coins of the same type are often dramatic.
