AC Compressor Cores

Anybody in here know anything about them? I'd like to learn how to separate the cores from the scrap. I grabbed a few out of my barrel in the garage in case anyone can take a gander at these pics and share some knowledge?

are there issues with the pics not showing up here also?

Little confused what your asking. Dont throw them in the steel pile, sell them seperate.

I do sell them separate, but some are worth more than others. Rebuilders are in demand for certain ones, and they have different core values. Some are scrap for numerous reasons, whether it be overstock, bad clutches, cracked housing, etc. I'm looking for someone who knows about the different core values and how to easily identify which ones are worth more than scrap value.

I bring all my AC Compressors to RAS Cores in RI
They have a list but I just throw them all in a barrel and they sort them
Some I get $20.00 plus for >> Some just scrap money
as you pointed out >> Some are scrap for numerous reasons, whether it be overstock, bad clutches, cracked housing, etc.
