Why these two coins have different KM number? I can't find any difference.

Hahahah. No problem.  

Hi you guys, if you do a forum search you will find that this has been discussed at least once before, but not sure if we ever had a definitive answer?

Yeah okay. I know that we talked about that before but let's define that now.
I think that we should delete the second one and leave just one of them.
Who agrees?

According to the data shown on this very website they have different diameters (although Krause labels them as the same size)

The difference is about 0.1 mm and You can't call that a difference!!
