Studio handheld focus stack of my favorite old, well-worn (and slightly dusty) Canadian penny.
Pentax D-FA 100mm F/2.8 WR Macro plus Raynox DCR-250 with off-camera diffused Godox AD180 Flash. Twenty-two frame focus stack at 2:1 plus a slight crop to remove stack edge artifacts. Frame is about 11mm wide here.
