These aren't tinnies but are Lapel pins that denote the wearer was awarded the U-boat Badge.
The dark one is WWI and the brass on WWII.
They look pretty good as they have the fluted stick pin. But please wait for more opinions.

The WWII U-Boat stickpin looks like a good original but I'm not convinced the First war pin is good. The back of the WWI pin looks like a bad cast with many imperfections and an original pin soldered onto the back. Just my opinion.

Thought that myself Al, but I'm not as familiar with WWI stick pins.
The casting inclusion between the wreath and sub, kinda sink it.
