Prussia 1/24 thaler contemporary counterfeit?

Weight 1.5 g and diameter 20 mm. Could this be a contemporary fake? The details seem pretty poor quality.

In case you didnt had the link, here is your coin in Numista: https://en.numista.com/catalogue/pieces18155.html

I know almost nothing about counterfaits, but Diameter its ok, weight not but probably its because its too worn? The thing that i see that not match too much is the 2 feathers under the A (watch the photo in the link)

Lets see if someone else comes over here, now i want to know too

No worries, this kind of coin has a very low silver content and they do not often age well.

As for small differences, very common for there to be different stamp varieties.
