Just looking at the pictures I would say it is not even gold plated never mind made from gold. If it is base metal, and I suspect that is what it is, you might get $20 for it, maybe more maybe less. Personally I would pay no more than $5 for something like this.

My Oma (grandmother) had something similar she was very very much a follower of the Royal's she couldn't afford much and it was something that she had as a prized possession. She lived in Wolfenbuttel regardless of collectable value to me that was something that provoked warm memories. Thank you for sharing :)
