My grandpa told me to sell some of his polo shirts, one of them is this one. How much can I sell it for?

Not sure if it's genuine, Claude AI says it is.

I also have a YSL, St. Michael Marks & Spencer, and Pierre Cardin polo shirt I want to LC but I'm not really sure where I can get it checked, if anyone could help me out it would be much appreciated.
