What are these blades worth?

Greetings gentlemen,

I found a guy with some old Solingen blades.
One is an Edaco and the other says First Class, both have
Solingen Germany stamps.

Ive never heard of Edaco before and seen High Class but not First Class.

What do you think? How much do you think I should offer for them?

Just trying to get some feedback because I cant find any info on these anywhere...

Red, I haven't seen them before. Are they listed here?

Already checked there, no listings for either...
