Thank you for your help and patience.
The presented object appears to be an antique probable Roman bronce coin with the measurements of 23.20 X 21.30 mm and 3.77 X 4.34 mm. The coins show two heads on each side no writings or inscriptions are visible because of the strong corroded surface. The side with the bigger green stains shows facials features which reminds of emperor Nero wearing a Hellenistic aureole crown. The head-on on the other side is not identifiable but reminds in its iconography on the coin production in one of the many Roman provinces.
This piece is in bad condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 15 to 40 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.
With kind regards,
