Liverpool 2001 signed team shirt

[Zigster]

I've had this shirt for 22 years and I've often thought of selling it but have no clue where would be best.

Nicky Barmby gave me it as a gift I have no certificate but have recently found out I can get it authenticated

Full squad 19 autographs 2001 treble Cup winning year

What would it be valued at ?
is it worth framing and authenticating ?
