in steve's video a copper basket is used to reverse plate the pins could this also work on silver pins? I am asking because some of the pins i have are half gold and half silver plated. If it does can I use the nitric to separate the two? Thanks for any anwsers

Silver plated?
Are you sure?
If they are, silver will strip equally as well-----but silver and gold, plated on a common item, sounds like a very strange combination, at least to me. It is well known that both silver and gold will migrate from one to the other at room temperature, as they will also do on copper based alloys. It is for that reason that a nickel barrier is plated on brass pins prior to gold plating. Otherwise, after a time, the gold is completely absorbed by the pin.
Is it possible that the silver you speak of is nothing more than nickel?
A test with Schwerter's solution will tell the tale readily, or you could dissolve the plating and do a test by other means. DMG would disclose the presence of nickel if you know how to accomplish the test.
