Value and Rarity

Because these are authentic vintage pieces made in Germany, they are considered collectibles by eyewear enthusiasts.

I see that “Canal” on one side in golden and on other side is more silvery. I this it was repaired at some point- see pictures for details.

I don’t have original box for them.
