Rogers Model 2S 2a/2

Hi all. I've come into possession of a pair of Rogers Model 2S 2a/2 Speakers:

Speakers. Model 2S 2a/2
Impedance 8 Ohms
Programme Power Rating 100Watts
Colour Black
Size 8.5” x 9” x 13.5”

Stands. Black
Quality. Heavy Metal
Sand filled
Size 14” High

I was just wondering what the general opinion on these speakers are and also how much they may be worth?

Thank you very much in advance,

Michael
