Hi this is my first post, hope I'm doing everything right :)
I need help to Identify a coin, here is how and where I found it.
FindingI live in Denmark, and was walking around a construction site. It is on a grassy hill, pretty close to the center of the town. They where removing some of the dirt, and I walked through the site around 6pm after the workers had left. I noticed the coin. It was around 20cm beneath the ground, that I found it.
DimensionsDiameter = 1.9cm
Here is a picture, it's showing the two sides. And the last one is the real color, without the light from the lamp.

The image is not as good as I had hoped, but I can read what it says.
On one side, there is a cross. The text around it is "**NETAL* ECEN S 1559" the * is letters I can't read/see.
On the other side, there is a two headed eagle. With the text around "**PERIAL**SCIVI*" The rest is unreadable :(
Hope you guys and girls can help me out, thanks for your help :)
