“3-Star Integrity Quest: Accuracy Confirmation” Campaign (Round 2)

Quick Overview

Join our “3-Star Integrity Quest: Accuracy Confirmation” campaign to ensure the accuracy of our gold and silver coin testing app. Help us identify potential false positives in 3-star results, which indicate high confidence levels. Open to all app users, the campaign offers a $100 reward for the first confirmed 3-star false positive.

Participant’s Process

  1. Spot a Questionable 3-Star Result: Use the latest version of our app (2.0.11 or newer) to test your coins. If you doubt the accuracy of a 3-star result, proceed to the next step.
  2. Verify on Your Own: Ensure the 3-star result is repeatable and isn’t due to misuse of the app or external noise(*). Ensure that you are using the latest app version.
  3. Report Your Findings: Use the “Report last test” feature in the app to report suspicious 3-star results. Please put “3-Star Quest” in the email body. We will do a first analysis.
  4. Remote Verification: We may ask for a video of your testing process; including measurements of coin’s weight and size.
  5. Send in the Coin: If further verification is needed, send the coin to our office.
  6. Assay Analysis: Our experts will first validate the 3-star rating. Should further analysis be required, a third-party will perform an in-depth composition analysis of the coin, employing the potentiometric titration method or an equivalent technique.
  7. Receive Your Reward: The first participant to uncover an incorrect 3-star result (**) will earn the reward.

(*) External noise checks:
Some background noises may not be audible but are detectable by the app. Open your app and start a test without doing anything; the app will record background noise. If it shows “Not enough data …”, it means that the 3-star result is not due to background noise.

(**) Incorrect 3-star result:

  • Silver coins: actual silver content less than 10% of the stated/nominal value.
  • Gold coins: actual gold content less than 5% of the stated/nominal value.

Key Points

  • Duration: From 1st November 2024 to 30th June 2025, or until a false positive is rewarded.
  • Reward: $100 USD (minus bank transfer fees) or equivalent for the first confirmed false positive.
  • Privacy: Winner’s identity partially disclosed based on preference (partial email, initials, region).

Important Notes

  • Destructive Analysis: The assay analysis is destructive. Coins sent to our office will not be returned in any case and become property of our company.
  • Postage: Participants are responsible for shipping fees. A $10 USD or equivalent reimbursement is provided for the reward recipient.
