I must be sittin' on a small fortune. Down my cellar I have about 40# each of virgin R12, R22, and a pretty full bottle of 134A. I only had the 134A to have something to make a couple bucks on someone's car if needed. I'm retired and got rid of all my gauges, etc., as far as anyone knows. I don't know of any refrigeration equipment, commercial, that I've ever worked on that used 134A. I could probably get rid of it all for $20/lb. if I needed to get rid of it quick. The 12 & 22 is worth more, depending on how bad someone needed it. None of the vendors around here have 22 on their shelves, and R12 is gone (but there's still a lot of old equipment that uses them.) The consumers pay.
I never priced that 1234YF, both my cars have it. $55/lb. is ridiculous!
