The isotopes of nickel range in atomic weight from 48 u (48 Ni) to 82 u (82 Ni). [9] Natural nickel is composed of five stable isotopes, 58 Ni, 60 Ni, 61 Ni, 62 Ni and 64 Ni, of which 58 Ni is the most abundant (68.077% natural abundance). [9] Nickel-62 has the highest binding energy per nucleon of any nuclide: 8.7946 MeV/nucleon.
This made the new coin heavy, in terms of weight per $.01 of face value, compared to the three-cent copper-nickel coin. The bill passed without debate on May 16, 1866.

An average 70 kg human body is about 0.01% heavy metals (~7 g, equivalent to the weight of two dried peas, with iron at 4 g, zinc at 2.5 g, and lead at 0.12 g comprising the three main constituents), 2% light metals (~1.4 kg, the weight of a bottle of wine) and nearly 98% nonmetals (mostly water).
