How Much Gold is in an Olympic Medal?

Olympic medals are symbols of excellence, dedication, and triumph, but have you ever wondered how much actual gold is in these prestigious awards?

So read on for some interesting facts about the composition of Olympic medals, the tools and techniques to evaluate them, and precautions to consider.

Composition of an Olympic Medal

Modern Olympic gold medals are not made entirely of gold. The International Olympic Committee (IOC) has specific guidelines:

  • Gold Medal: Contains at least 6 grams of gold, with the rest being primarily silver.
  • Silver Medal: Made of pure silver.
  • Bronze Medal: Made of copper and a small amount of zinc or tin.

Gold medals are predominantly silver (about 92.5%) and plated with a thin layer of pure gold. The exact composition can vary slightly depending on the host country.

Items Needed to Analyze a Medal’s Gold Content

To determine the gold content in a medal without damaging it:

  1. Precise Weighing Scale: To measure the medal’s weight.
  2. Ultrasound Thickness Gauge: To estimate the thickness of the gold plating.
  3. X-Ray Fluorescence (XRF) Analyzer: A non-invasive tool to determine the medal’s elemental composition.
  4. Reference Materials: A known standard of gold or silver for calibration.

Precautions to Be Taken

Before you start analyzing:

  • Avoid Damaging the Medal: Olympic medals are priceless artifacts. Do not scratch or cut them.
  • Use Professional Equipment: Rely on non-invasive tools like an XRF analyzer.
  • Consult Experts: If the medal is a collectible, involve a professional appraiser.

Step-by-Step Instructions

1. Weigh the Medal

  1. Place the medal on a precise weighing scale.
  2. Record its weight in grams (modern Olympic gold medals typically weigh 500-600 grams).

2. Analyze the Surface Composition

  1. Use an XRF analyzer to scan the surface of the medal.
  2. Note the percentage of gold present. For modern medals, this should be at least 1% of the total weight (approximately 6 grams).

3. Estimate the Thickness of the Gold Plating

  1. Use an ultrasound thickness gauge to measure the gold plating’s depth.
  2. Cross-reference this with the weight to estimate the gold’s volume.

4. Calculate the Gold Content

  1. Multiply the medal’s total weight by the percentage of gold found in the analysis.
  • For example, if the medal weighs 556 grams and contains 6 grams of gold, gold makes up approximately 1.08%.
  1. Use this figure to calculate the approximate monetary value of the gold based on current gold prices.

5. Confirm the Core Material

  1. Re-scan the medal with the XRF analyzer to confirm that the core material is primarily silver.

Tips and Tricks

  • Know the History: Different Olympics have slightly different medal compositions. For example, earlier gold medals (pre-1912) were made of solid gold.
  • Use Non-Destructive Testing: Avoid outdated methods like acid testing, which can damage the medal.
  • Research Market Value: The gold content is only a part of the medal’s value. Historical and collectible significance often outweighs the material worth.

Conclusion

While an Olympic gold medal contains a modest amount of gold, its true value lies in the achievement it represents rather than its material worth. Using professional, non-invasive tools, you can analyze its composition to satisfy your curiosity without compromising its integrity. If you’re lucky enough to own one, treat it with care—its worth transcends gold and silver!
