First time poster, so if I did it wrong or am in the wrong place, kindly let me know.

I've got an older Bianchi that I am trying to learn something about. The serial number is stamped into the lug at the top of the seat tube - 2F 602. There is a decal on the seat tube the says "Made in Italy". There is nothing that tells me the model of the bike or the frame tubing used. Please help if you can tell me the year it was made, the model, possibly the tubing type, and maybe how much you think this bike is worth? Thanks for the help! A few pics are below.
