Criminal, Open Light Bluish Gray Jacket over Prison Shirt, Dark Bluish Gray Legs, Black Hat, Missing Tooth (3626c Head)

This particular LEGO City Criminal minifigure is desirable due to its unique head print featuring a missing tooth and scar, giving it a distinct, memorable look. Minifigures with unique facial features tend to be more popular among collectors.

The fact that it only appears in one retired set, the Police Dog Van, further increases its appeal. Collectors often seek out minifigs from retired sets to complete their collections or to own a piece of LEGO history. The prison outfit adds to the character's recognizability within the LEGO City theme.

This Criminal minifigure is moderately rare due to its exclusive appearance in the Police Dog Van (4441-1), which was released in 2012 and has since been retired. This single set appearance limits the overall quantity of this minifigure in circulation.

While not a regional exclusive or special edition, the limited production timeframe of the set contributes to its scarcity on the aftermarket. It's not the hardest minifigure to find, but it's not one you'll stumble upon easily.

The investment potential for this Criminal minifigure is moderate. Its value is likely to gradually increase over time due to its rarity and the popularity of the LEGO City theme. The unique head print also contributes to its collectibility.

As the Police Dog Van set becomes increasingly scarce, the value of this minifigure is expected to rise. Keeping the minifigure in excellent condition will maximize its potential return. It's not going to make you rich, but it's a solid addition to a LEGO minifigure investment portfolio.
