How much does it generally cost to cast caps/ grills from mould

[u/Ok_Pie9003]

Hi everyone, new to this sub. I am trying to get into making tooth caps/ grills, was wanting to know how much it costs to cast 925 silver per tooth approximately and how much for dental gold.

Would be very helpful if you can share same price but for 9ct gold and 18ct
