The is designed on a slope so gravity will help bring the coins down to their designated slots. The coin slots are at exact diameter of each coin in order of right to left Dime, Penny, Nickel, and Quarter. The walls keep the coins going straight to their slots and to avoid the coins from missing off to the side.
The ramps allow the coins to drop from their slots and slide of the ramp to a accessible location where you can collect the coins. The dividers divide the different coins from each other.
Labels show which coin goes in what section of the dividers.
The off balanced Nut causes a vibration that helps the coins get down the ramp to their coin slots.
Each coin had their precise measurement in millimeters.
