One year ago, you purchased a rare Indian-head penny for $13,000. Because of the recession and the need to generate current income, you plan to sell the coin and invest in Treasury bills. The Treasury bill yield now stands at 10 percent, although it was 8 percent one year ago. A coin dealer has offered to pay you $12,100 for the coin. Compute the holding period return on this investment. Round your answer to two decimal places.
