1175 years of Staßfurt, 800 years of municipal law, 1980 commemorative medal

Found in my grandad’s loft as we were clearing it out. In box so in good condition.

Only place I can find an example of it on the internet - is it of value or does it have any specific meaning?

I don't know anything about this. But here is a link to it on Numista
