1897-1907 Stock certificates

Have three certificates dated 1897, 1902 and 1903 from The Canada Mutual Mining and Development Co. Limited totalling 700 shares.

There’s a fourth one dated 1897 but says ‘Not Transferable’ along the side, for another 400 shares.

There’s a fifth one from Ontario Quebec Cobalt Mining Company, dated 1907 for 100 shares

All five certificates, on the backside (to my understanding) were transferred on the same date in 1936 to another person.

What the hell do I have here?
