Regarding the coin thickness, a bronze byzantine follis' weight varies between 10-15 grams. Thickness would be between 1.6mm - 2.6mm.
A quarter weighs 5.67 grams and the diameter is 24.3 with a thickness of 1.75mm. Assuming a similar diameter to thickness ratio, the thickness of the Constantine coin would be 2.2mm. Steering towards a heavier coin may be more satisfying when actually holding it. Calling the thickness at 2.5mm.
