• Coin value and attribution depend on authenticity, date, mint, variety, grade, surfaces, provenance, market liquidity, fees, metal assay, and current spot prices. Images and arithmetic cannot replace expert authentication or in-hand grading.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Retain weight, diameter, photographs, references, transaction fees, and price dates; verify valuable pieces with recognized catalogues and qualified independent experts.

• Grading Submission Cost Per Coin

  Allocate grading, shipping, and insurance costs evenly across submitted coins.

• Appraisal Average Value Per Item

  Average the stated appraised value across collection items.

• Duplicate Swap Value Difference

  Show the nominal value difference when swapping a duplicate coin.
