I'd like to get some state quarters (until now I only have got New York). I offer similar coins from Germany. Since 2006 each year one of our "Bundesländer" (federal states) appears on our 2€ piece, so far seven different. The value of 2.00€ equals 2.49$ currently, so I assume one of those for 10 state quarters is a fair trade, isn't it?
Of course I'd also trade other combinations of euro coins if you have a better idea. I just liked how the respective motives correspond
Anyone interested?
