Definitely one of the favorite player activities is the pin trading between teams. Each of the players and teams participating during the week brings collectible pins to trade. The pins are elaborately decorated, specific to each team, their respective states and hometown's, and are essentially the player currency of CASV. Trading for every pin available is a pursuant most players will spend all of their available free time on until they are finished.

Designing your own team's pin takes careful consideration as the cooler the design is, the more sought after they are by the other teams. Pins design can incorporate a variety of design options like glitter paint, led blinking lights, "sliders", "danglers", and "spinners". If the actual baseball play is the fun part of the CASV trip, pin trading is the serious business part of the player experience.
