Step 1

Coin is cathode and copper wire is anode. The copper wire at anode decreases in mass and oxidation half-reaction takes place. The coin at cathode increases in mass and reduction half-reaction takes place.

 

Since both the electrode is copper, the overall reaction can be

Step 2

From the overall reaction, the half-cell reaction can be written as,

 

The half-cell oxidation reaction is
