Need help identifying a Polish coin

I recently found this coin from my grandmother.I found the same coin on the Internet, it turned out to be temporary Denier Princes Polonie - Boleslaus I the Brave. But for some reason my coin has a different backside from the one I found on the Internet. There is a museum and poorly visible inscriptions. What does this mean? Help determine the value of this coin 

It means that it is a tourist token from whatever museum is shown where the one side is a copy of the coin.  The real coin is silver, yours looks to be brass.
