10 Pfennig 1971J varieties

[everycountrycoins]

Hello,

 

I just noticed that I have three different varieties of 1971J 10 Pfennig coin from the German Federal Republic. I know that most of you won't care about this, but I'm curious to know if all three are listed in a catalog other than the Krause catalog (which lists 2). Here is my description of the three (let me know if you care enough for me to try to take pictures):

 

Tall vertical with just a very slight hook at the bottom

Large J with the hook being almost as long as the vertical

Small J with a fairly standard hook

 

Thanks to all who look into this for me,

 

Bruce
