Hello Guys, I've been looking into diecast models of Joal types and must say they look quite detailed which adds to my interest. My question is , are Joal diecast models heavy or do they just look like they are? It looks like they might be from pictures I've seen so I've added one below. Can anyone provide me with any more information about the models and weight? I've looked on TractorMad but would like a little bit more information before purchasing anything like this.

They are by a different manufacturer, that's all. Different brand name, like Cadbury Vs Galaxy.  
 
It is my experience that all good die cast models are heavy. They would certainly stand up to a child, but these are too nice to allow to be all bashed up.

I think though that they will last pretty well when played with. They are fairly sturdy most of them. I haven't any Joal specifically but the few die cast models that we do have look like they would be a little tough for a wee one to hurt. Just keep the box neat and tidy when it's taken out.

They would never be mint condition in my household. I was the girl on the block that loved to play with all the tractors and dump trucks.   I do wonder though, how many collectors there are out there for things like this. Anyone know?

As the model ages it becomes more rare, and that is when the collectibility increases. Some things will just never gain much value because the market at the time was saturated; like the Royal wedding memorabilia from a couple of decades ago. Only the stuff that was easily damaged, but maintained in tip top shape will be worth anything.
 
Same goes here. If you want to keep something as an investment, buy two and keep one locked away. Other wise it won't have much value in the future.

These particular toys are designed for the slightly older child in my opinion, and your right there a lot tougher and last longer. These are the benefits of products like the Joal diecast models, recommended if your kids like to use there toys in the garden a lot.
