I made myself a small rig for this project so i could easily hold and rotate the coin, but this is not a must.
You'll also need to find a pre 1965 half dollar. 1964 was the last year for 90+% U.S. coins.
Start by lightly hitting the coin on the edge and then rotating the coin using the hex nut as a guide for how far to rotate.
