Tom, I believe this was handled on WehrmachtAwards.com. I have found, directly from an Iowa veteran, a cased DKiG with the dotted date and, from another motel buy veteran, an uncased dotted version.
Also, several other collectors have found these directly from veterans and had posted this on the other site.
I have no doubt these are period originals and were a variation by hallmarked 20. While I have found several golds, only two 20s were with the dotted date variety and, as I have found only one silver, I can comment on a dotted date silver one.
