Germany 10 Pfennig

I wanted to add 10 Pfennig 1971 J and j to the year list of this coin here on Numista but I was asked to post it here on this forum.
So - in year 1971 there were two types of this 10 Pfennig coin with mintmark "J" - one with small mintmark and one with large mintmark.
You can check this for example here: http://www.catawiki.com/catalog/coins/countries/germany/1141879-germany-10-pfennig-1971-j-small-mintmark and here: http://www.catawiki.com/catalog/coins/countries/germany/803109-germany-10-pfennig-1971-j-large-mintmark
I have both these types so I am sure that it is right. Please, change it.
