I’m making some coins via lost wax right now. I want to essentially give them away, likely here. Is there a site that allows me to list items, where the buyer pays the shipping cost and then they can add whatever amount as a tip or other? Essentially I want to be able to drop these coins online, post the link in PMG and then whoever gets there first can buy them. If anon wants to pay the $4.35 for me to ship it, cool. If anon wants to pay $4.35 to ship and add $20 to help me continue my minting projects.
The coin will be particular to pmg, cast in copper for my first design and casting. My hope is to be able to maybe make enough to get a die made to strike my next batch. I’m a stay at home dad with time on my hands and casting is a hobby of mine. I’m bored.

Is there any way to by silver ore raw? I want to crush, dry and melt my own. I’m having trouble finding some place online. Colorado would be preferable because of its proximity to cut down on shipping costs.
