Best Options?

if you're looking for numismatic value most here like coinsandcanada.com ... if you're looking for melt... any number of sites that deal with silver melt prices for 80% will suffice.. I personally like using gatewestcoins web site and seeing what their buy price is for silver and their sell price is and using that as a gage..

I agree with AgCoinAu. If you're looking for silver prices, check online. An example would be (124) Not Allowed - Auto-Removed (Tried to add link but the site removed it?). If you check the individual coin at Numista.com it will also tell you the spot price. Here's one for silver quarters: ( http://en.numista.com/catalogue/pieces369.html )
Or if you're really looking for very accurate values just go to Kitco.com and check the silver spot price and then multiply by 0.149 for every silver quarter (There is approximately 0.6oz of pure silver per $1 face value of Canadian Silver 0.800 coinage).

if you're looking for numismatic prices, CoinsandCanada.com is good. But remember to multiply modern coin prices by 0.80 to make sure you're not overpaying on un-updated prices.
