I have a bunch of silver plate and E-Wasted just added it to his buy list. He has it as silver plated brass. Is there an easy way to determine what the silverplate is on ?
I tried a magnet on it and its all non magnetic. Its all labeled silver plated or such. Do you file off some of the silver to see if copper shows ? Not sure but Im thinking of
cashing it in . Your input / advice is appreciated.
Thanks

Brass is much harder. You can also hit it with a torch to see if it melts to distinguish the two.

I've been paying about $10 to $25 a ounce for nickel plated brass that's about 100 years old.
