Hand over and Hand in
According to the dictionary we "hand in" to someone in authority and "hand over" to someone oficially or formally.

Examples:

I handed in the money to the police.
I handed over the money to the police.

Can' these two sentences mean the same? If I give something to the police, this is, from my point of view, something oficial or formal and police guys are people in authority.

Examples:

I handed over the letter to my boss.
I handed in the letter to my boss.

Here it happens the same.
