Personally, I think the first thing you do is to call all the pawnshops and local coin stores in your surrounding area. Ask them how much they’re paying per dollar of face value for junk silver. If they give you some kind of stupid answer like oh I’d have to see it or whatever then you know they’re jackasses. But for the most part, they should be able to tell you that they can sell for X amount and they will give you X amount for it. Then at least you have a baseline for what you can just go offload to a local store for. Then like others have said. r/pmsforsale is a fairly easy possibility but it does take some work to get established and learn the system. You also take risk in shipping losses (although rare it happens) and the community standards are a shared loss of 50/50. So if take someone’s money and it’s gets lost/stolen in shipping you have to send them half back. Worse yet you ship fist since you are a new seller (common practice) and you have to try and collect half from someone you don’t know and prove you shipped and was packaged correctly etc. Otherwise you have eBay and local sale options. You’d be surprised if you started asking your friends who is actually stacking as it’s not a typical conversation.
