I got the five piece set. Coin specs are 1 Peso: diameter 37mm, width 3 mm. 40 Centavos: diameter 27mm, width about 2.3mm. 20 Centavos: diameter 23mm, width about 2.2mm, 10 Centavos: diameter 18mm, width about 1.5mm. 5 Centavos: diameter close to 16.1 mm, width about 1.4 mm. All coins have a reeded edge, except the 1 Peso that has a smooth and imprinted edge with slightly faded fleur-de-lis. All coin details are a match for the real coins and silver plating is excellent. These are great replicas for collectors and teachers! I wish there were more sets like this for other coins. Good value add product!
