A unidentified German cardboard emergency coin or token

Göttinger

Today I found this unusual emergency coin or token in a bulk of coins I was sorting through.
Do you have any information about it, probably a catalogue reference or a similar coin / token?
Any suggestions are welcome.

The coin/token seems to be made from pressed white cardboard with a (uniface?) tin foil plating.

The inscription reads "Ewada Darre Dresden" (Ewada kiln in Dresden), a company that operated between the very early 1920's and the mid 1930's (probably even earlier, the documents I found are not clear about that).

Even though the denomination should be 10 Pfennig, it's much smaller than a 10 Pfennig coin, probably closer to a 5 Pfennig coin.

The coat of arms of Dresden has a lion and stripes, quite unlike this very Imperial-looking German eagle, so I would presume the design was to encourage acceptability among a populace still used to seeing that eagle on German official coins.
