Here's the breakdown:
Dimes:
The dimes minted in 1945 are composed of 90% silver and 10% copper. Each dime contains 0.07234 troy ounces of silver. Considering the current silver spot price of around $23.88 per troy ounce, the silver value of each 1945 dime is approximately $1.73. Since there are three dimes, the total silver value of the dimes is 3 x $1.73 = $5.19.
Quarter:
The quarter minted in 1930 is also made of 90% silver and 10% copper. Each quarter contains 0.1808 troy ounces of silver. At the current silver spot price, the silver value of the 1930 quarter is around $4.31.
Therefore, the total silver value of the three 1945 dimes and the 1930 quarter is approximately $5.19 + $4.31 = $9.50.
Please note that these values are based on the current silver spot price and may fluctuate over time. Additionally, the actual value of the coins may be higher or lower depending on their condition, rarity, and numismatic value.
