I have two Ben Franklin half dollars: One is a 1961, and the other one is 1958. I also have three Walking Liberty half dollars: They are very worn and as best as I can tell the dates are - 1920, 1929, and one unreadable. Upon further investigation, I have learned that my two Eisenhower dollars are not sliver. I also have a few more none silver coins that have zero silver content, but I still keep for their sentimental value. Like coins from my family members birth years, and coins that are not silver, but not widely circulated anymore (a few Kennedy 1/2 dollars one a Bicentennial!).

I've had these coins sitting in a cut glass bowl for years - it's only added to when I am lucky and find a coin. Soon I would like to start adding silver dimes, nickles, and silver grams (these are in my low wage price range). Recently because of my financial circumstances, and my increased interest/awareness in silver I have started to educate myself about silver and sliver coins. I have found the websites http://www.coinflation.com and http://www.silvergrambars.com/calculator to be particularly helpful.  

I would love to have a Silver Canadian Quarter as my 6th sliver coin!
