What character trait do Jem and Scout illustrate with their ambivalence about taking the pennies?Chapter 4

Jem and Scout find the pennies in the tree. Indian head pennies are supposedly good luck, so it is understandable that the children would be excited and motivated to take the pennies. Yet, they also know right from wrong, and they know that these pennies are someone else's property, and taking them from someone else is stealing. The fact that they are hesitant to take them shows them to have a strong moral background, and a good sense of right and wrong.
