Refrigerant for older cars

I know I’m new but I want to let anyone who might be interested who has an older original ac system that I have 30lb tanks of (1) 409A and (1) 401A. These are the direct replacements for R12 still wrapped in cellophane around the valves. So if interested let me send pictures of the tanks and what else to verify it’s not a scam.
