How Would One Get An Image Put To Coin?

I just watched a very interesting doc on history about Bruce Lee, and for 32 years on the planet he sure made an impact, an his influence is still common to find in every day life. I thought he is an image that would always hold value to countless people, and could not find a solid silver coin of Bruce or gold even. I know if there was a 1 oz gold coin with his image on it, an say one of his quotes on the back, it would be something I would pay bit above spot price for if I had that kind of money available....

He really thought ahead of the curve and was ahead of his time, from training to philosophy. He would drink protein shakes made of raw meat, an egg other vitamins, in fact creating items you could find in one bottle today at a local GMC. He could do 2 finger push-ups, an amazing 1 inch punch, which generated torque that boggled the mind, much of the UFC today is everything he believed, the ability to adapt, via combining many different forms of technique from many different cultures. He did shock therapy, which can be found in physical re hap offices today....

Plus many say he was key in bridging the gap between Western an Eastern culture, so that to me makes him worthy of at least being on a solid piece of 1 oz silver....

The doc said China had recently accepted him, via plans to make a museum, many large statues being erected around the world, so it seems like a commemorative coin would be a no brain-er for some one who made the impact he did....

I just Bruce as an example as he was fresh in my mind, and was wondering if some one had a great idea to put some one on a coin, is there actually a process to make it a reality, via poll or something?

I really suggest watching this on history if you catch it on again....
