Sand casting copper coins and more

Today i will be using up the rest of my left over scrap copper that we took out of a walk in chiller and bar. I will recycle it into copper bullion bars and coins.
I will be trying for the first time to cast a double sided coin with green sand. I have done lots of open cast coins before as well as double sided coins in Delft Clay but this is the first time using green sand
Green sand is generally used for bigger items but the sand i have got is super fine so I was hoping to get very good quality results and i did.
Its not as good as Delft clay but they came out super good quality for green sand and i am very happy with the results and the camera does not do it justice. they look way better in person.
