My prices at the yard today.

Most of the scrap yards give you scrap steel prices for motors up here

My yard is nice enough to leave price lists on the counter. They seem to only change them about once a month. Maybe because the prices are so low.

Irony Aluminum .13-.20
#1 Brass 1.15

There are a few more catagories but you get the drift.
