Ancient small bronze coin. Probably Greek. Apollon?

Hi, I would like to ask for help on this one: Bronze coin, 16 mm in diameter, weight 4,03 gr. Some parts of the coin are very well preserved while some are completely off. Obverse: could it be Apollon? Reverse: hard to say, it looks like a heart with hair , a horse head maybe? I have to admit a lack of imagination here.






I would appreciate any help, ideas on what might be on the reverse side for example , just anything that would help me to find out more. Many thanks
