A drawer is divided into 9 square boxes, creating a 3*3 grid.
Your task is to create a "magic square" by putting a distinct amount of money in each of the boxes in a way that all of the 8 sums (vertical, horizontal and diagonal) will be the same.
Only standard American coins are allowed, i.e. 1,5,10,25,50, and 100c.

What is the minimal amount of coins ?
Show their distribution.
