German coin that needs to be added

To Whomever Does This,
I have come across a 1922 German 10 Pfennig coin KM#20 with NO mintmark. This coin does appear on the NGC website. Can we get it added to Numista? (Yes....it is KM20 NOT KM26, been doing this long enough to know the difference).
Thanks,

do you mean this? https://en.numista.com/catalogue/pieces1953.html
Edit: Sorry I overread the 1922, my short time memory seems to be a bit faulty
You'll have to ask donmart, the referee of Germany 1871-1948, to make this change.

Thanks, I have sent the message to donmart!
