Need to find old compenhagen sign

My dad saw this Copenhagen sign when driving to mexico for our summer trip last year and stopped and offered the guy $100 for this old antique sign. Just an old circular compenhagen sign with their old slogon on it. Anyways the guy wouldn't sell it, so I'm going to try and find it online and give it to him as a christmas gift. So If anyone can help me find an auction or link to were you think I may be able to find it that'd be great. Btw if you link me to a place where I can buy the sign for a decent price I'll send you like $1 paypal

 

copenhagen tabacco or the city?

 

You mean this one?
