I had a can of R-12 on the shelf and a fill hose for it I no longer needed. Sold it on ebay for ~$60. Most others I saw advertised asked $100 for a can. Have prices dropped? Strangely, I found that can left on a bench over the river when out jogging ~10 yrs ago (nobody around), so grabbed it knowing it was gold, plus recall I still had R-12 in one car then.
