How to reset a game object to its original rotation.

Question

I have a game object that when clicked, moves upwards a little, and rotates to demonstrate selection. I am trying to get it so that when I click the object again (deselect it), the object moves back down to the original way it was facing.

Moving the object down again is no problem, however I am having trouble getting the object to rotate, so that if faces the way it was originally facing. This is the latest code I have tried, however when I deselect the object it simply moves back down and keeps its new rotation.

 public Transform originalRotationValue;
 float rotationResetSpeed = 1.0f;
 
 void Start () {
         originalRotationValue = gameObject.transform;
     }
 
 void Update () {
     //rotate selected piece
     if(isSelected)
         gameObject.transform.Rotate(0, 1, 0);
     //otherwise rotate it back to its original rotation
     else
     transform.rotation = Quaternion.Slerp(transform.rotation, originalRotationValue.rotation, Time.time * rotationResetSpeed);
     }

What am I missing/doing wrong?

You're saving the object's transform, but should instead save the original rotation!

 public Quaternion originalRotationValue; // declare this as a Quaternion
 float rotationResetSpeed = 1.0f;
 
 void Start () {
     originalRotationValue = transform.rotation; // save the initial rotation
 }
 
 void Update () {
     //rotate selected piece
     if(isSelected)
         gameObject.transform.Rotate(0, 1, 0); // this rotates only 1 degree!
     //otherwise rotate it back to its original rotation
     else
         transform.rotation = Quaternion.Slerp(transform.rotation, originalRotationValue, Time.time * rotationResetSpeed); 
 }
