Abstract: A method for enhancing the appeal of a sporting event at which wagering is allowed utilizes a dual-function ticket having two parts to produce a collectible souvenir having true rarity. A first ticket part records details of a placed bet, and is arranged to be cashed in to collect on a winning bet, while the second ticket part identifies the sports event and the participant on which the bet was placed, thereby serving as a souvenir having potential value as a collectible. Rarity of the souvenir ticket part is assured in that it can be obtained only through placing a bet, and the integrity of a collectibles aftermarket in the souvenir ticket parts is maintained by providing authentication means on the ticket to foil counterfeiting.
