RE: Where to buy silver in Canada?

Well I just want to have something that's tradeable in case of emergency down the road. My great uncle died and left three chests full of silver and gold coins for his kids but it was for an emergency. He didn't trust the banks very much and when he died there was $140000 in coins in these chests. I am just thinking that if I pick up some affordable silver that I could put away, it would be a good thing to have on hand. I do like a lot of the coins but I was thinking of silver for trading as silver, not as a piece of art.
