How do you test siver at home without acid?
If you have acid it is very easy to make a big mistake, and without acid it is hopeless. It reaches a point where you refuse to buy anything you don't recognize. That means pure silver and stamped sterling and nothing else.

I finally just stopped dealing with them unless they brought me a recognizable coin or ingot.
