Good numismatic shopping in Northern Germany?

I'm planning on going on holiday to Northern Germany and hoped to find something for my collection while there. I can't see any places on the outing map on here.

Preferably it should be in the Schleswig part, or at least not further south than Kiel in Holstein. Any shops, secondhand stores or alike in that area, with good/cheap collectorshopping? :)

Thanks in advance!

Hi there, 

I'm not sure that you can find a “good”numismatic shop in Schleswig (Sleeswijk  in Dutch), despite that I would like to advice to visit the saturday market instead. I'm pretty sure that you will find some collector items in there.

Viel Spass!
