Ring counts per ounce

I have listed below the ring counts per troy ounce in Sterling Silver. I will list for Copper and Gold Fill as soon as possible. It does however, take a long time to count those tiny little rings. In the meantime however, both copper and gold fill is lighter than silver, so you do get more rings per troy ounce.
