In 1998, a Hasbro advertising campaign asked the public to vote on a new playing piece to be added to the set. The candidates were a bag of money, a bi-plane, and a piggy bank. The bag ended up winning 51 percent of the vote compared to the other two which failed to go above 30%. This new token was added to the set in 1999 bringing the number of tokens to eleven. Another 1998 campaign poll asked people which monopoly token was their favorite. The most popular was the Race Car at 18% followed by the Dog (16%), Cannon (14%) and Top Hat (10%). The least favorite in the poll was the Wheelbarrow at 3% followed by Thimble (7%) and the Iron (7%). The Cannon, and Horse and rider were both retired in 2000 with no new tokens taking their place. Another retirement came in 2007 with the sack of money that brought down the total token count to eight again.
