Introduction: Loose Change (coin) Sorting Trays.

Make loose change sorting trays from plastic bins. Drill a pile of holes (just the right size) into some plastic bins, stack them, and empty your Piggy Bank in and shake.


Step 1: Making Change Sorting Trays.


What you need:

- Stackable plastic bins. (one for every coin size you need to sort)
- Drill
- Drill bits, 11/16", 3/4", 7/8" (U.S. coins)


Step 2: Short Play by Play..

Real quick... (if you're actually interested, please watch the 6 min. video)

Drill random (or precisely arranged) holes in the first bin with a 7/8" drill bit for nickels to fall through.

Drill random (or precisely arranged) holes in the first bin with a 3/4" drill bit for pennies to fall through.

Drill random (or precisely arranged) holes in the first bin with a 11/16" drill bit for dimes to fall through.

I used a 5/8" bit for the dimes, and it needed to be worked over with a tapered bit.

Remove the loose plastic..
Stack the trays..
Toss some change in and shake to separate.

    First of all, great instructable. Secondly, I have come up with a design for a change sorter that might be easier to operate.It's a design, I havent made one yet. Sorry it's so small. If you cant read the text it says,"The farther down, the larger the hole associated with the coin."and,"The larger coins will slide over the smaller coin holes and end up falling into their own hole probably leading to a tube or something for containment."

    (I know I'm replying to an old post) I'll take that concept, simplify it (in 17 hours), and then make my simplified design (not involving holes; it's just the same idea).

    Thanks for sharing. I already found commercial version of this somewhere.

    I wanted to sort quickly all my coins as I dumped them in my coin box (huge shoe box by now...).

    The problem I came up with was the precision of the holes required. Mine was similar, more like this one...

    It failed because too often toonie would get stuck in my loonie hole, however in the video it look well crafted.

    I'm going to transform my shoe box so it has a drop box, so I can simply literally dump all my coins and get sorted in seperate cases.

    See this video...

    .. for ideas on how to make coins "flow". This could be useful on having them lined up, so they don't jam in the previous sorter I linked to.

    Thanks!

    Fizzxwizz: I'm not sure how that design would work. All of your coins will have to slide over the holes one at a time. If any coins were on top of one another (like a dime on a quarter) they'd both drop in the quarter slot. Also, the smaller coins may slide right past the holes meant for them if they are not lined up properly. It looks like all of the holes need to be to one edge and the "slide" also needs to be angled so as to keep all coins sliding down that edge. Kepp us informed if you make it work.

    >If any coins were on top of one another (like a dime on a quarter) they'd both drop in the quarter slot. That's probably why the boxes are nested and arranging in decreasing size - coins are supposed to drop through holes larger than themselves, because then they can get to a hole only they can fit through farther down the stack.

    Not referring to the boxes Chavez. I was talking to Fizzxwizz and referring to his slide design.

    Oh, I see. Sorry, your post looked to be pushed all the way to the left, so I thought it was a response to the article, not another comment.

    thanks for the comment and the video.. another great idea. Mine works quite well, thanks.
