I found a really bad preserved coin in an 8kg-world-coin-lot and I am unanble to identify it but curious about it. Hope someone knowing this type of coin is around.
Here a color-scan and two black&white photos:



I think I can make out something like an eagle facing left in a circle with traces of an inscription on one side and a lion in a circle, facing left too, on other side. But that's all. I think the coin alignment lies around 90° but I'm unsure about wehere the top of the two sides really is..
Here some more data:
Diameter: around 25mm
Weight: 5.58g
By view, the coin is made of copper or bronze.
The lion remindet me of the old kingdom of bohemia, but I can't find a similar piece in any online catalogue...
