Historically, buying physical coins with a credit card was a popular method for "churning" credit card rewards. In the U.S., individuals would buy $1 coins from the U.S. Mint using rewards cards that offered frequent flyer miles. These coins were then immediately deposited into bank accounts to pay off the credit card bill, effectively allowing users to gain free miles for minimal effort. Today, most mints and retailers have restricted this practice by applying surcharges or categorizing such purchases as "cash advances," which carry high interest rates and no rewards.
