okay the yard i've been going to the past couple months has been giving me these prices for stuff and i'm wondering if its too low and if i need just to go somewhere else.

Steel and Auto parts
mix- $0.08
Clean- $0.10



Brass
mix- $0.98

Aluminum
Sheet- $0.49
Cans- $0.50

Copper
#1- $2.25
#2- $2.20
Bright Wire- $2.35

Other Salvage
Wiring- $0.25
Mixed Non Ferrous Metal- $0.40
Mixed Ferrous- $0.05

All of it is done by the pound and i'm just curious if these figures are too low (like i already said)
