1. What is 90% Silver Coin Weight?

The weight calculation determines the actual silver content in 90% silver coins based on their face value. These coins (like pre-1965 US dimes, quarters, and half dollars) contain 90% silver and 10% copper.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( FaceValue \) — Total face value of coins in dollars
• \( SilverContentPerDollar \) — Ounces of silver per dollar face value (typically 0.7234 oz/$ for US 90% silver coins)

Explanation: The formula calculates the pure silver weight by multiplying the total face value by the standardized silver content per dollar.

3. Importance of Silver Weight Calculation

Details: Knowing the actual silver content is crucial for investors, collectors, and precious metal dealers to determine the intrinsic bullion value of silver coins.

4. Using the Calculator

Tips: Enter the total face value of your coins in dollars. The default silver content (0.7234 oz/$) is pre-filled for standard US 90% silver coins but can be adjusted if needed.

5. Frequently Asked Questions (FAQ)

Q1: What coins are considered 90% silver?
A: In the US, this includes dimes, quarters, and half dollars minted before 1965, and dollar coins minted before 1936.

Q2: Why is the silver content 0.7234 oz per dollar?
A: This accounts for the exact silver content across all denominations. For example, $1 face value in 90% silver dimes, quarters, or halves contains 0.7234 troy oz of pure silver.

Q3: Does wear affect the silver content?
A: While wear reduces the total weight slightly, the silver content per dollar remains essentially the same for valuation purposes.

Q4: Can I use this for other purity silver coins?
A: No, this calculator is specifically for 90% silver coins. Other purities (like 40% or 99.9%) require different calculations.

Q5: How do I calculate the melt value?
A: Multiply the silver weight by the current spot price of silver per ounce to get the approximate melt value.
