A Change for Our Change

We have been dumping our spare change into a jar for years, and every time it fills up and we have to count it all, we are miserable, so I decided to buy a segregated coin holder. I put way too much thought into which one to get, but finally settled on this one because it has the smallest footprint.
It is working out really well, but there was one problem. In dim lighting, it was hard to tell which slot was for which coin since the labels were the same color as the rest of the unit.

I solved the problem in no time using a Sharpie to highlight the raised labels. Our coin sorting has never been so efficient.
