Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
This is brass, not gold, unfortunately!
Can you post a photo of the painted portion?
This is a mid-century brass trinket box, American, in the shape of an egg.
While the details were likely painted by hand, overall it was mass produced. I know this because an identical one recently sold on Etsy.
Another identical one recently sold on eBay but I can't get the link to copy.
The value would be $25-$35.
I see you have not yet rated/accepted my answer. How can I help you further?
