JSP Silver Acid Test - Questions on the results

So the coin i know is silver turned blood red, then left a creamy color when wiped off

but the thing i wanted to test: fizzes yellowy/orange then turns dark gray, almost black.

everything else fizzes yellowy/orange and stays that way.

soo what does this mean?

Dunno... my acid tester turns green when not silver. Have you checked manufacturer's site? Also, try wiping away where you did the test. If there's base metal showing that's a dead give away, too.

Maybe some silver plate with base metal underneath.

It means its not silver

Silver will always turn red and when wiped, leave a red spot on the cloth

yellow orange sounds like spelter/pewter reaction.test a fishing weight,a nickle,other known objects.wont take long for you to know the reactions.when the silver solution turns greenish(snot)its silver over copper.

silver turns creamy grey when acid tested, if you can use 14k testing acid its clear and not black so you can see whats happening usually when something is silver plated it is first copper or nickel plated so the acid will bubble different colores
