Is a rooftop commercial HVAC R22 still usable?

I have two rooftop HVAC units that were taken off of a school about 8-10 years ago. They were working when they were removed. Now they need to be cleaned up a littl and checked out. I am wondering if the units are better as scrap or as a unit. The local recycler is paying 1.32 per pound for the coils, and 2.85 for clean copper tubing. I cant find the information about the units as a whole, but the compressor information is below. I live in South Central Oklahoma if that makes a difference.
LENNOX                                    R-22                 LOW SIDE TEST PRESSURE: 150 PSIG MIN SERIAL #: 840768178                 MODEL #: 2A056AG1 CATALOG No: 98C90 VOLTS HZ PH MIN OPERATING                    LRA                 VOLTS                    53 460     60 3 400 380/460 50 3                THERMALLY PROTECTED
Can you tell what the tonage is? Thanks for any information you can provide. If there is a market for the units or the parts separately could you give me an idea of where to look or how to market? Thanks

Let it sit. According to the trade paper the thieves will be along to collect it.
