Treasure Hunts (TH): Also known as "hunts," these cars are less rare than STHs, but still considered valuable by collectors. They have a production run of approximately 1 in every 1,000-3,000 cars. THs are usually identified by a special symbol, such as a flame or circle, on the card or the base of the car.
Variations: These are cars with slight differences in paint, tampos, or wheels from the standard mainline release. Variations can be common or rare, and their value depends on the specific variation and its desirability to collectors.
Prototypes: These are pre-production models of Hot Wheels cars that are not typically released to the public. Prototypes can be extremely rare and valuable, especially if they are in good condition.
Factory Errors: These are cars with defects or errors that occurred during the manufacturing process. Factory errors can include paint blemishes, missing parts, or incorrect tampo graphics. Some factory errors are highly sought after by collectors and can command high prices.
Event Exclusives: These are cars that are only available at specific events, such as the San Diego Comic-Con or the Hot Wheels Collectors Convention. Event exclusives are typically produced in limited quantities and can be difficult to find.
Online Exclusives: These are cars that are only available for purchase online, typically through the Mattel Creations website. Online exclusives are often produced in limited quantities and can sell out quickly.
Promo Cars: These are cars that are produced for promotional purposes, such as by car dealerships or fast-food restaurants. Promo cars are not typically available for sale to the public and can be difficult to find.
