Common Mistakes & Best Practices
Common Mistakes to Avoid
These are the most frequent errors users make that lead to unreliable test results:
- Selecting a different coin - The most common mistake. Always match the coin in the app to your physical coin
- Using incorrect weight - Remember: 1 oz = 31.1 g (not 28 g or 30 g)
- Using imprecise diameter - Even small differences (1-2 mm) invalidate the test
- Choosing the wrong material - Verify you've selected gold or silver to match your coin
- Dropping the coin - Affects the sound recording and can damage the coin
- Pinging too frequently - The app may filter rapid pings as background noise. Wait 1-2 seconds between pings
Best Practices
Follow these guidelines to get the most accurate results from your genuine coins:
Before Testing
- Use the coin catalog whenever possible - Select the exact coin rather than generic models
- Verify the displayed parameters - Check that weight, diameter, and material match your physical coin
- Measure if uncertain - Use a scale and calipers to confirm specifications
During Testing
- Ping 2-3 times - Multiple tests increase reliability
- Wait between pings - Allow 1-2 seconds between each ping
After Testing
- Remeasure if results seem wrong - Double-check your coin's weight and diameter
- Verify your selection - Confirm you selected the correct coin in the app
Following these practices helps avoid false negatives on genuine coins and ensures you get reliable, meaningful results every time.
