I run a business that's about as small as it gets — a car wash in Maryland with four employees, including me. If I did things like the government, I wouldn't be in business very long. In fact, for the past 12 years, I've been using $1 coins as change for my customers. And guess what? People like them. Think about it; if you buy a $12 wash with a $20 bill, would you rather get eight dollar coins or 32 quarters back in change? I see my customers struggling to insert worn-out bills into our bill acceptors. Then I see customers using coins. Guess who's frustrated, and who's washing their cars while the others are still feeding in bills? It's easier, more reliable and helps me run a more efficient business by reducing costs. Indeed, according to the American Public Transportation Association, it's about six times cheaper for businesses with high levels of cash transactions (like mine) to process coins versus bills.
