Lighthouse Coin Tubes for US Nickels (Suits Australian $2 coin) (21.21mm)- Box of 100

There is a point at which coins stop being individuals and become a quantity. That is the point at which you need tubes.

These are Lighthouse square coin tubes, sold a hundred to a box, sized for 21.21mm coins — US nickels and, conveniently, the Australian two-dollar. Each tube measures 25 by 25 by 83mm, is made of archival-quality plastic, and is built to be unbreakable. The square profile is the quiet genius of the thing: they stack without argument and, unlike the round sort, they do not roll off the desk at the worst possible moment.

It is the squareness that Jonah appreciates, with some feeling. He once spent an evening filling round tubes, set them in a neat row near the edge of the desk, and turned away to make coffee. By the time he returned, three had made a slow and deliberate escape to the floor and a fourth was clearly considering it. He gathered the coins by torchlight, muttered something unkind about the laws of physics, and bought square tubes the very next week. He has not chased a coin across the floorboards since.

A hundred tubes will hold more coins than you currently admit to owning, which is rather the point.

A collection counted is a collection you can finally stop worrying about.
