German Silver Spoon

I have this silver spoon for a long time and I always wondered if it as a antique value or just silver value. I am a noob for antiquities so I need your help.

Spoon has big BL initials on one side and small JK initials + small german bird from the flag on the other side.

Grateful to advance.
