Hi,
we're talking about the km616.n, so all you really want to know is, if it's the .1 to .7?
First a little help generally where it helps if you can speak a bit of Danish:
http://www.danskmoent.dk/artikler/1771kgsb.htm with an English summary
Now to the km numbers
The coin is
NOT
.4 "DANKSE"
.5 "DANAKE"
.6 "DNASKE"
.7 "M.K" in sted of "K.M"
so that leaves you with ONLY 3 possibilities
.1 is out, since the point in the date is IN the date and not BELOW the date, here I suppose the KM catalog shows a km616.1 in the image, I might be wrong, but anyway the K.M. distances are not the same!
so is it a .2 or .3?
According to the drawings in the Pedersen article, the link above, your coin was minted in Altona, now Germany, because of the big distances between the "K", the ".", the "M" and the "." Unfortunately KM only differentiates between a "serif" top of the "C"s and the thickness of the "C".... not very precise at all.
My coin has a "C" thickness of 1.82 mm, but is that thick or thin?
Here is my coin, in a rather bad state, but it ressembles your coins features?

That's all the help I can give you. If you figure it out in the end, please tell me?
