Coins from 1937-1942 (Beaver Reverse) weigh 4.54 grams, with a diameter of 21.21 mm and a thickness of 1.7 mm. They have a composition of .99 nickel.
In 1937, the beaver motif was introduced for the five cents after being first considered for the ten cent coin. A dot appears after the date on all 1937 coins. This was done to balance the design.
