To look inside and understand the network of diecast collectors, there are certain ideas, concepts and jargons one needs to know the basics of.To start off, the most basic and standard measurement used to classify certain diecasts are scales. Scale is an indication of the relative sizes of the vehicles. For example, a popular scale, 1/18 would mean that the diecast vehicle is one 18th of the size of the real vehicle. Written another way, the real car is 18 times larger. Accordingly, a 1/43 scale car would be smaller because the diecast is one section of the size of the real car, divided by 43.
