Help with IPS and unknown Wert-Marke

Hello all,

I've seen the design on the Princely states before but my eyes get crossed trying to find it.

Any ideas on the Wert-Marke?

And the US quarter is for size reference, but I can give accurate sizes and weight if needed.

 

Hi,
The IPS coin is this one, https://en.numista.com/catalogue/pieces37121.html. Year is 1926 (KM#143.2)

Found some info on the Wert-Marke coin here, http://www.coinpeople.com/index.php/topic/16354-wertmarke-huh/

Wonderful. Thank you.

I'm hoping someone will have an idea about the G.D.K. on the wert-marke.
