Scrap Silver Rings as Bullion

Description

As pictured, 4 rings and a decorative wire, all in at least 90% silver.  That weird ring in the back is, yes, an early school project made of melted silver coins.  The other 3 rings were tested to be sterling.  The decorative wire was tested also to be silver, and assumed to be at least 90% silver, but its weight is minimal.  Total weight of all items is 22 grams.  They are heavily tarnished.  These are being sold for bullion purposes, so I don't have the ring sizes.
