Junk Silver (Quarters)

So that means that regarless of condition...8 quarters would be 1oz for sure. Now here is another question... How is the silver content accessed? I mean ok you hold onto the quarters because you know that is has silver content, but isn't the silver kind of usless unless it can be melt and reused? Isn't melting canadian coins illegal? I realize that these are noobie questions...but I have a handfull of these pre 1966 quarters and I am trying to understand the mechanics behind holding onto them or not. I'm looking for guidance and information since I haven't really explored this avenue really. Only really delt with silver bullion. Any insight would be appreciated! CHEERS!

Thank-you Carl for some insight. I would definetly check out dates before I did anything...I always to. I've been looking at quarters and dimes as a way to make money long term or short...don't really care when...I only know that in the end thses coins are for making money so I am wanting to learn from anyone here on how that is accomplished. I myself would not go through the trouble of melting down these coins so I have a lot to learn on how to, why and where to be involved in this...or even if it's not a good idea for me. Thoughts please. CHEERS!

@biggfredd Thank-you for the website! Wow, that beats having to do my own math! LOL
The coins being sold as coins for its content is what I was looking for. I didn't know if it was done like that (in its coin form) or if it was sold to be processed. This is of cource with the exception of important dates. What would a silver scrap place give you for 1 quarter if melt value is at $5? Or...If I were to purchase a lot of quarters...what would be the price that I would expect to pay? I dont want to go by ebay prices because of such a marked up value...but if I were to be looking for a deal....what would that deal look like? I don't want to rip people off and I don't want to be ripped off as either. Thank-you all for your insight. :-)
