Interest rates are near record low levels. They’re so low, it may seem like you might as well just stuff your money under your mattress or stash it away in a cardboard box since it’s hardly earning anything.

His bank was ultimately able to reassemble the bills so he could be reimbursed by the U. S. Mint for about $1,000.
