Treasures of the future

Collecting objects is a need that is as fundamental to humans as possessing a moral conscience; some can escape it, but most are slaves to it. 

Hobby collections provide their owner with distinct character. When I was younger I used to fill Fruitopia bottles with pennies. I don't think it is a coincidence that I was also very frugal. I no longer collect pennies, and I am no longer frugal. 

I would like to begin a collection that will be worthy of being passed on through future generations. I'm thinking along the lines of plastic animal toys.
