You can also save some space and aggravation by buying holders for nickels to put dimes and pennies into, as well as, your nickels. The most often found coin is the "penny", followed by the "nickel" and maybe some dimes thrown in the mix. Soooooo, buy a bunch of "nickels" holders and you're all set. A supply of "half-dollar" holders will cover the quarters and occasional halves you'll find.
When putting pennies and dimes into nickel folders; and the quarters into the half dollar folders, just place the staples closer to the window at the 12, 3, 6, and 9 o'clock positions.
These cardboard holders are excellent for "everyday" finds, but you'll want the plastic holders for the valuable ones.
