A US quarter is 24.26 mm in diameter, giving it an area on each face of 462.2441 square mm (A = pi * r^2). Is also 1.75 mm thick, meaning that the edge (assuming that it was smooth - that is, without giving effect to the increase area brought about by the 119 reeds on the reeded edge) would have an area of 133.3763 square mm (A = 2 * pi * r * h). Thus, the total surface area of a US quarter would be 1057.8645 square mm. A Canadian quarter is 23.81 mm in diameter, giving it an area on each face of 445.2548 square mm (A = pi * r^2). Is also 1.60 mm thick, meaning that the edge (assuming that it was smooth - that is, without giving effect to the increase area brought about by the reeds on the reeded edge) would have an area of 119.6821 square mm (A = 2 * pi * r * h). Thus, the total surface area of a Canadian quarter would be 1010.1916 square mm.
