Coin Roll Experiment

I grabbed the heavy metallic coin by its milled rim! It was thicker than my boots, cold, and solid. Rolling it was the only way to move it across the shelf. I set it upright, braced one foot against a thick book cover for leverage, and shoved hard with both hands. It spun forward in a smooth, ringing circle! It rolled past a row of paperbacks, wobbled, and dropped flat with a loud clang against a metal bookend. Heavy cargo transit confirmed!
