mantle autographed ball

any idea on the price a mantle ball would fetch in the following condition:
faded sig, faded mlb logo.
official rawlings mlb
no cert (signed for me in memphis, tn card show) - i could probably send it to psa. based on condition of cards in relation to baseballs, i'd say this would be a 4 or 5 due to fading and debris on the ball.
would it be worth it to have it psa/dna'd and cubed by them?
