I do not know if anybody noticed this yet, but...

there are 2 varietys of this coin: mintmark close to the edge and a little bit more far away

Interesting. So which version is more common?

Let's see from a serious collector's point of view.

If I want to collect both the varieties from all grades, I have to get:

2 x UNC;

2 x BU (Taken out of the annual BU set of 2013);

2 x Proof.

Total = 6

Now if we add edge varieties (Type 'A' and Type 'B'), then there are six more. So 12 in total...
