The Saxe-Gotha-Altenburg 1772 coins for the death of Friedrich III are groschen and double groschen.
The groschen is in Numista at
https://en.numista.com/catalogue/pieces97187.html
The double groschen (1/12 thaler) is at
https://en.numista.com/catalogue/pieces97184.html
The coins are both the same size (21mm); one is double thickness.
My coin weighs 4.2 grams; which one is it?

Then you have the double groschen, the groschen weighs rougly 2.14g according to past auction.

not sure if it's correct that they have the same diameter listed here.
likely a mistake from Krause catalogue which we have copy pasted here.

On the 1/12 thaler, Krause notes "Double-thick flan", so they should have the same diameter.
Thank you for your assistance.
