Gold Particle and Coin in a Gold Pan

Coins can be used as a reference point during image-based analyses. By placing them next to objects of interest within photographs or videos submitted for evaluation—such as those involving insects, plants, or other small items—the size of these subjects becomes easier to interpret and compare accurately by experts analyzing the images remotely.

Placing coins in photos serves several purposes:

1. Scale Reference: Coins provide a known measurement that can help determine the actual size of objects within an image.

2. Enhanced Accuracy: By understanding scale, analysts can make more precise assessments about what they are examining.

3. Consistency Across Images: Using standardized coin sizes (e.g., quarters or dimes) ensures consistency when comparing multiple images.

Overall, including coins in submitted photos aids experts by providing a clear and consistent reference for size estimation during their analysis process.
