In a nickel and copper electrolytic cell, nickel would likely be the anode since it typically undergoes oxidation to release electrons into the external circuit. Copper, on the other hand, would be the cathode where reduction reactions occur.
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.

Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
Pure copper collects at the cathode during electrolysis because copper ions are reduced at the cathode, gaining electrons and forming solid copper.
Because the cathode is where reduction takes place, meaning the it gains electrons. When it gains electrons, it attracts the copper cation (Cu^2+) and as the copper cation reaches the cathode, it picks up the electrons from the cathode, and is deposited as solid copper (Cu). This results in the cathode gaining mass over time.
