Diecast Collections Diecast models refer to toy models that are produced under die casting methods. These make excellent collectible toys. Diecast collections can be passed on for generations. Many of these models are produced as limited edition products. Once a specific model has sold out, it is never produced again. This makes for rare and unique collectible models that grow in value as they age. These toy models became popular in the 1950s. They were often gifts for special occasions and given by and to loved ones. Model sets include cars, limousines, various aircrafts, and specialty motorcycles. New age varieties include artfully scaled and technically designed cranes, construction trucks, military models, and mining models. Diecast toys come in varied scales. The largest models are on the 1:12 scale and usually average 37 cm in length. Models at this scale are targeted at adult collectors. The most popular scales used in the Australian manufacture of diecast models are 1:24, the choice scale of Franklin Mint, 1:43, the most popularly chosen scale for all diecast model cars worldwide, and 1:76 (compatible with H0 model trains). Australia's diecast model manufacturing company, Top Gear, produces Trax Models. Top Gear was founded in 1986. Trax Models diecast cars are released regularly, every two months. All Trax Models buses, stateliners, etc. are marketed as "Trux." Top Gear operates on a strict Limited Edition policy in the manufacture and marketing of Trax Models. Because of these highly successful marketing strategies, diecast models will continue to thrive in the toy industry for decades.
