Identification
The strict definition of an antique pertains to something that's at least 100 years old. However, vintage classifications are considered for toy car collections. For example, 1925 marks the end of the vintage toy car period in the United States.
Early Models
Well-known cast iron models were made by the Hubley, Arcade and Dent companies. These cars resemble full-size vehicles, and they were most popular from the 1880s through the 1890s.
Toy cars made from steel were produced in the 1900s. Makers of steel models included Buddy Firestone, Dayton and Tonka Toys.
Late Models
White metal toy cars largely replaced cast iron models around 1945. Dinky Toy made detailed, white metal cars that have been growing in popularity among collectors.
Collecting
Collectors often focus on a particular type, subject or manufacturer to build a toy car collection. A focused collector also is less likely to be fooled by reproductions.
The monetary value of a toy car is affected by its condition, and that value is increased if the car is kept in its original box. Try to find cars that don't have marred surfaces and have their original tires intact.
Benefits
Toy cars can be less expensive than many other types of antiques, partly because they're more readily available. Therefore, even new collectors can find affordable models to start their collections.
