What is This Sketch Card Worth?

Hey Guys

I have A Kemba Walker 1/1 Sketch Card and Technically its also jersey Numbered because he Wears that Number.


What do most People Think This is Worth?

I found a Very Similar One But I don't Know what to take from that- eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

Thanks In Advance,
Harsha

Sketch cards aren't worth much NBA wise. I'd be happy with $20.
