Know this is an old thread, but came across it the other day while researching what the best thing to do with this big a** jar of pre-64 silver coins I "inherited" last year when my Granny passed. Papaw started sticking them in there when they changed from silver before he passed in '70, Granny kept them for me cause she knew I dealt in silver/gold - coin & scrap jewelry. After checking for rare dates & mint marks, etc., I didn't know what the cost vs. reward would be on melting them, or just plop the giant bag on the scrap guys desk. Here's what I found... With a small ceramic jewellers crucible, graphite "cup" crucible, & 1, 5, & 10 t.o. graphite molds, and a standard MAPP torch, I was able to raw melt about 9 t.o. in almost 2 hours. Yes it's legal to do it. Yes, if like myself you have the things needed to refine it, test it, & stamp it, & the reputation in your community that you know what you're doing, you can. But it's cost prohibitive...not the canister of MAPP gas, but also the crucibles, & my times worth more than that. I'd stick to buying silver/gold lots on Craigslist/eBay. Let the silver scrap pile up till you need a fork lift to move it as it's not worth squat now, & when you've got your t.o. of scrap gold, smelt & refine it...payoff is WAY better.
