I would like to know what you think about my last aquisition, this Ostmedaille Marked 19 (E. Ferdinand Wiedmann) + It’s original package.

Are both pieces original ?
Do I have something to be concerned about ?
Is there any detail you think deserves more attention on this example ?

I’m a new collector so I’d appreciate any advise about this piece and maybe details I should always look after when buying decorations.

Thank you in advance !
