How uniform is your silver (or gold stack)? I have a strong desire to have my silver in only a few different types, but I have found, at last count, that I have over 50 different types of silver in my "stack" and over a dozen different types of gold. This bothers me. Is yours relatively uniform, or all over the place of randomly collected silver based on what was ever the best buy at the time? If so, what makes up the bulk of your stack? I'd like to keep my focus on 1 ounce Silver Maples and Britannias, supplemented with an American and Canadian junk pile. My gold has stayed focus on 1 oz Gold Maples plus various close to 1/10th ounce pieces.
