Pre 1968 Canadian Dimes

Each coin 1920-1966 when minted weighed 2.32g of 80% silver equalling an ASW (Actual Silver Weight) of 0.0597 troy oz.

A 1967 dime when minted weighed 2.32g of 80% or 50% silver (so generally accepted as 65% since the mintages are roughly equal) equalling an ASW (Actual Silver Weight) of 0.0485 troy oz.

Add "ASW" in your search to come up with more results maybe?

Right now the coin calculator puts the price of a pre-1968 dime at $1.22 USD or $1.33 Cad.

For higher grade examples or older ones you can look them up at http://www.coinsandcanada.com/coins-prices.php Take the prices with the usual grain of salt though. If you're not sure about grading there is a (partially complete) grading guide as well with pictures http://www.coinsandcanada.com/coins-grading.php

My recent experience selling Canadian silver coins, other than really exceptional or rare ones is the majority of buyers, even dealers will offer about 70% to 75% of melt value at best. The ones I've met recently (mostly dealers)don't even want to talk about numismatic value. That's why I've locked the Canadian silver into a safety deposit box at the bank and it's staying there until silver goes back to about $30 CAD per ounce.
