Commando badge, one WWII the others 70ies?

[PLN]

I have those in my box. I got them many years ago.

The dagger one, I think is original WWII. Could someone confirm as well as tell me what it is precisely (Commando Brigade?)

The following one is certainly a reproduction or at best a 1970ies production.
What it is precisely (combined operation)?

As do not want to keep the second one what it is worth?

Thank you,
