The list of years is complete and has been verified. Most requests to add new year entries are sent for the wrong coin type. If you are sure you own this coin with a date that is not listed here, you can ask to have it added through the forum and include a picture of your coin in your message.
There is no mentioning of this variety in Krause (as it is for the 1970J). We all know Krause is great but it's not sacred. And your pictures don't lie. Unless one coin is a fake, but who will fake a 1 pfennig coin with a mintage of 79.304.000 pieces.
