Exact Dimensions of a Us Dime: Millimeters, Inches, Weight, and Visual Scale
Q1: Why is a US dime smaller than a penny?
A1: Dimes originally contained 90% silver, which held much higher market value than the copper used for pennies. The coin was kept small so its metal value did not exceed ten cents. When the US Mint removed silver in 1965, it maintained the traditional size so automated coin-operated machines would not need expensive overhauls.
Q2: How much does a standard roll of dimes weigh?
A2: A standard bank roll contains 50 dimes, representing a face value of $5.00. The coins alone weigh exactly 113.4 grams (4.0 ounces), excluding the minimal mass of the paper wrapper.
Q3: How can I tell if a dime contains silver using its dimensions?
A3: Pre-1965 silver dimes share the same 17.91 mm diameter and 1.35 mm thickness as modern clad coins, but they weigh 2.50 grams instead of 2.268 grams. In addition, silver dimes lack the visible copper stripe along the reeded edge.
