Coin Sorter

Trace each of the differently sized coins onto the bottom of separate rectangular plastic containers, except for the smallest coin, with a marker. If you have four different coin sizes, you will use four different  plastic containers but only drill into three of them.

Find a drill bit that makes a hole several millimeters smaller than the traced shape in each container. Drill several rows of holes with the appropriate bit for each container in the bottom of the containers. The holes should be spaced about  inch apart from each other. !lace the undrilled container on a table. Insert the container with the smallest drilled holes inside the undrilled container.

!ut the next smallest holed container inside the stack and place the largest holed one on top

"ollecting coins can be a rewarding hobby, in more ways than one. #hether you are looking to find a specific style of coin in a large collection or looking to sort a large collection for rolling, a method of $uickly dividing your coins by value can save you a lot of time. This simple design uses a series of shelves, with increasingly smaller holes until each shelf contains only one denomination.

"reate a vertical groove in each of the %foot%by%%foot grooved boards. The grooves should run perpendicular to the grooves made in tep ( and be  inch from the front of the board. To ensure that these grooves line up, one must be  inch from the left end of one board, and the other should be  inch from the right end of the other board. • •

crew the two grooved %foot%by%%foot boards to the remaining %foot%by%% foot board. The grooved boards should be placed atop the remaining board,

running along opposing walls, with their grooves facing each other. The shape created will be a s$uare missing its top bar. • •

easure the distance between the two grooved boards, and trim the & '(% inch%wide board so that it fits snugly between the two, and screw in place. The grooves on the three boards should all line up, so that there are four continuous grooves wrapping around the interior of the box, and the vertical groove should be on the end of box not closed off by the & '(%inch board. •

These holes may re$uire some slight sanding to work. To test a hole, slide a  penny and a nickel over it. The penny should fall all the way through, while the nickel should remain on the shelf. • •
