Decorative plaque ?

[digging65]

Hi,
I found this beautiful plaque last week in the forest around Porvoo.

Any idea of what it is ?

Plaque in in Bronze or Copper. 29 grams. Dim. 5,5 x 4 cm. In the back it looks like old fixation system ?

No inscription or marking on it ? Form is a bit like curve, look at the last photo !

Thank you for any hint, please post your answers also in Finnish.
Kiitos paljon !

Could it be from a piece of furniture or from a wall clock?

Could be, correct.
Seems more from a round object due to the curve shape ! Or part of a medal or broche ? Can't really figure out. Hope someone have seen this somewhere before.
Kiitos, tack Urmas
