A reward scheme has been developed to encourage collection of as many stamps as possible. Depending on the number of stamps collected, participants may receive bronze, silver or gold badges. 25 stamps earn bronze, 50 stamps earn silver and 100 stamps (a complete booklet) earn gold. The National Organizational Committee of the BTU holds an annual lottery for the previous year's badge earners every August. Prizes include domestic and overseas excursions, bicycles, tents, sleeping bags, and other travel-related items.
