You can judge the grade/quality of the sig by yourself-- you don't need PSA/DNA to tell you it's dark and bold or light. The autograph grade doesn't hold anything near the same weight as a trading card grade, as you one can fairly judge the sig condition via online scan. Whether or not the autograph has a number grade really is no big deal, having minimal effect on market value.

In the scheme of things, a small cut out picture isn't terribly desirable, but a bold Clemente signature on anything is. You can do a history search at Lelands.com to see Clemente prices.
