It is believe as legend has it, that round 50 cent pieces increase telepathic ability. So the more you have the more chance you have of becoming telepathic. Question answered, may this finally be put to rest.
I will answer then They DO NOT collect the 1966 50 for anything other than silver content. If they had no silver , then 99.98% of people that collect them now would stop. The guys and girls above are just being silly about the psychic ability being enhanced by the 50's. It is the sterling silver State $10 coins that actually enhance psychic abilities. I did read a study a while back about chronic constipation and there was something about 1966 50's in the story. I cant remember the exact story , but i think in the end it may have been from SS members swallowing dirty 50's and using the stomach to clean them and getting stuck. House may pop up and provide a link for us:
I have a few hundred I could sell you - it might just happen that you would be telepathic after that but only if you pay a really good premium!
They are just a damn sexy coin and great to look at and play with when they have been cleaned. Source: my left hand
FYI, australian 50c coins are octagonal. There are no "round fifties" it's a common symptom of the bite from the silver bug, along with other delusions of telepathy and space travel. Peoples infected have sporadic urges to drive trucks in reverse as well.
