Meaning of "Buck ten, buck fifteen, tops"

You get a look at him?

Little thing. Buck ten, buck fifteen, tops.

Maybe he’s Filipino.

The above sentences are in the movie Mr and Mrs Smith. Could you pls explain the meaning of the phrase buck ten, buck fifteen, tops.


Solution 1:

"Buck ten" means "One dollar and ten cents", or 110 cents. So it presumably means here 110 pounds, or about 50 kilos. Likewise "buck fifteen" means 115 pounds. So:

He looks like he only weighs 110 pounds, or 115 pounds at most.
