Old Bronze? Rom? Grk? Coin ID

Found in personal effects of deceased friend. Any ideas/thoughts at all about it would be helpful: I have no background whatsoever! Appears very old, very slightly off-center (attaching images... I hope that is the proper way to do this here.) Note that there is no "bust" image of a ruler on either side: one side depicts a building with pillars while the other depicts a gathered bundle of wheat as its centerpiece.
