Will anyone trade German empire 2,3,5,10, and 20 mark coins with me?

Dear Numista members,

I collect a lot of German coins particularly from the German empire era(1871-1918). The only problem is the only good coin store in my area either rarely or even never comes by these hard to find coins and so I am forced to buy from eBay for retail prices and I am tired of it. So I wanted to know is anyone is willing to trade any 2,3,5,10, and 20 mark coins with me from this era? If so that would be great! (I also collect from the German states period too.)
