WHEN YOU ARE DEALING WITH COMPANYS WHICH BUY YOUR SCRAP  GOLD, SILVER , PLATNIUM  AND PALLADIUM.  YOU SHOULD GET LOCAL EXPERT ADVICE FROM A LOCAL METAL EXPERT BEFORE YOU DEAL WITH THESE PEOPLE THAT ARE  ADVERTISING FOR YOU METALS.  THEY ARE RIP OFF ARTIST.  I HAVE A PIECE THAT I HAVE SENT TO THREE DIFFERNT BIG COMPANYS AND I GOT THREE DIFFERENT ANSWERS.  THEY ALL SAY THAT THE DO THERE OWN IN HOUSE TESTING.  I DID AT LEASE TEN TESTS FOR SILVER, WHICH SHOWED IT WAS NOT SILVER.  I DID TESTINGS ON THE PIECE MY SELF BEFORE SHIPPING. THESE PEOPLE ARE REALLY THE SAME WITH DIFFERENT NUMBERS.  I HAVE TALK TO THEM AND IT IS ALLWAYS THE SAME VOICES.  BEWARE.  THEY ALL ARE WITHIN A COUPLE BLOCKS IN NEW YORK CITY.
