Tubeo is correct, much of the information that you seek is available on the cartridge data base. But as to value, in unused condition, assuming that you have all orginal packing materials, you have over a thousand dollars worth of phono cartridges there maybe a couple thousand.
Supex cartridges are particularly highly prized as Sugano worked there before he started Koetsu. The wooden bodied Supex are the most prized and valued in the market place. The MM cartridges that you have are not generally collected but probably sound great.
I collect vintage MC cartridges and certainly have never had the good fortune of a find like that one. I do love my Supex though.
