(sorce: Iceberg Slim – Pimp, The story of my life)

The section that contains the word:

”He squeeled: Shine ’em up, hot shot! If I had your ’hand’ I would throw mine away. Get on bigtime. Shines ain’t but a dime. Shine ’em up!
I looked down at my stomps. They could stand a gloss all right.”

Background:

Slim walks down the street in elegant clothes and a shoeshiner man invites him to get his shoes cleaned. (The section above is what the shoeshiner tells to Slim.)

So what does he mean by ’If I had your hand I would throw mine away’ ?

thanks in advance
