Help with odd mark on silver spoons

[pamsjam]

Hello, I have 12 silver (plate?) berry spoons that are marked “12” on the back. One is also marked UHRBACH or UHBBACH with the 12. They are antique and are very thin. They feel like sterling, but not sure. Any feedback would be appreciated! 

Thanks,

pamsjam

Sterling, especially vintage/antique, is always marked as such somewhere. Can you post a pic for us? There is also a great site online that has marks and makers, just google 'antique sterling silver marks".

Thanks, I found what I needed. It is German 750 silver.
