If my prototype is successful, I'll make an Instructable. That'll give you plenty of pictures. ;-)

Yeah, it's working fine. Now I need to finish it. It'll take some time though, because I'm busy on my ball machine.

No, I haven't been building it because I ran out of green rods. But, I just bought 900 off of eBay. :-)

Its called your hands.  It would be very hard to make a sorter that you just dump pieces into, but I have an idea how.

No, you are supposed to use your hands, though.

Most real change sorters are just tilted sideways ramps for the coins to roll down and then fall through a hole that is just slightly larger than the coin.  The smaller diameter coins fall into their chutes first.  Shouldn't be hard to do if you can size up something for the coin to fall through.

Take a look at the links in the comments.  There was the banker's one where the slots were not holes but two bars spaced apart that would accurately size the hole as the coin slid past.

Sorry, I don't do Knex. I think a bunch of connectors and rods will do it.  Maybe if you post this topic as a knex gun that shoots and sorts coins for ammo you may get a response from the regular knex crowd.  Good luck.
