to the CCF, from a collector in Sydney.
Just remember, if you are a young mum, keep your coins well away from preschoolers.
When my son was about two yrs old, he swallowed a coin, and choked on it.
Everything went silent, and as every mum knows, toddlers are rarely silent. I saw him in the loungeroom looking up with a pained face, with no sound. I rushed straight at him, turned him upside down, and slapped him quite hard between the shoulders.
Out popped an Aussie 10 Cent coin, I felt like I had just hit the jackpot
! 
Not 24 hours earlier, I had read on just a subject in a mother craft magazine.
He is now an avid collector of English coins and has a complete portrait set in silver shillings, of British Monarchs, Charles 11 to Elizabeth 11. covering a period of more than 400 years.
Although I am now a grandpa, I still collect any interesting coin that comes my way from packet change, just as a kid would do, and have been doing this for the last 15 years or so. So get in there, and encourage your elementary school kids.
