missing mint for two German 10 mark coins

"1875 338,679"
All other coins from Baden have mint mark G so I think it should be
"1875 G 338,679"
but I don't know for sure.

"1873 1,500"
The picture shows mint mark for 1803 A and all other coins from show AMecklenburg-Strelitz so I think it should be
"1873 A 1,500"

You can submit a request to fix these.

I thought that's exactly what I was doing. I'm new to the forums here. Is there a better way to submit a request for a change?

You can go to the bottom of the page and click the "modify or add data on this page"

Then, go to the "mintage field"

Finally, go to the column where it says "mint letter", and add the mintmark that is missing.

Thanks! Done.
