Gold coin ENGLAND 1700-1800 ??, approx 28mm, 10 grams?, Year?,still Fine (ws)

Description

It is a gold coin but also very thin-walled (more like a piece of sheet metal), it is probably a German coin, estimated from the 1700-1800 century, but could it be older or younger?
There are 3 men on the front of the coin and a coat of arms on the reverse.
Unfortunately, however, the coin is a little more bent (presumably through a tooth test for the authenticity of the gold, as was common in the past!)? So that the inscription and the pictures are no longer clearly recognizable.
The weight of the coin is around 10 grams ??
Since the surface is also heavily worn.
The conservation status is at most still Fine"
For the specification information, I cannot take any guarantees, as it is only approximate information!
Unfortunately, however, I could not find out about this coin whether it is rare? !!
Maybe there is someone who can give me a little more information.
Unfortunately it is not my area either !!
