text: how do i find out online how much canadian coins are worth? my mom left me a bag of coins dating between 1900 and 1975 they are canadian i want to know if any could be rare? canadian coins are very collectible and you need to make a list of all the coins and either by a coin book or ask someone who has a book to look up the value.  after that you can pick out the rarest and then try to sell them if you wish.   i have a coin book and a blog feel free to stop by and put the list of what you have in the comments. or you can always check http://www.ebay.com/  good luck i hope you find something good.
