Roller Derby Girl

The Roller Derby Girl is a desirable minifigure due to her unique design and limited availability. Her distinctive helmet, torso print with the '49' logo, and the scar under her eye make her instantly recognizable and appealing to collectors. As a character from a popular collectible minifigure series, she represents a specific theme and adds diversity to any collection.

The fact that she only appeared in one series of collectible minifigures enhances her collectibility. Collectors often seek to complete entire series, making each minifigure within that series more valuable. Also, the unique parts, especially the head print with the scar, are highly sought after for customization and MOC (My Own Creation) building.

The Roller Derby Girl's rarity is moderate. She only appeared in the 2013 LEGO Minifigures Series 10, meaning she was only available for a limited time. While Series 10 was widely distributed, the blind-bag nature of the collectible minifigure series means that obtaining her required luck or aftermarket purchase. She is not a regional exclusive or special edition, but her single appearance contributes to her relative scarcity on the secondary market.
