NTR metals has the best return that I can find. They have quite a
few locations and pay you within an hour of delivery. I ship my scrap
to them, have always been happy with the return and gotten a check
within a day or two. No refining fee for straight silver scrap. They
don’t give a hoot about solder, impurities or any of that stuff.
You do need to be registered with them, but the app is online and
simple to fill out. They have NO minimum. The only wrinkle is that if
you have mixed up your metals and want a return on all of it, there
is a modest refining fee and the stuff has to go to Dallas.

Go to Commercial Refining and read. Their price lock-in is very
useful in this volatile metals market.
