## Methodology
Goldback premiums use the Goldback reference rate rather than raw contained-gold spot. Goldbacks are reported separately and excluded from ordinary gold statistics.

Statistics use a 30-day rolling window. Premiums are frozen when listings are scanned and are not repriced. Medians are weighted by each listing's total fine-metal content, normalized to troy ounces, with no per-listing cap. These are observed asking premiums, not sale prices. Product rows include only catalog-matched listings. Rows below 5 samples are hidden. Asks under US$100, numismatic listings, and warning-flagged listings are excluded. Source listings are public Reddit r/Pmsforsale and r/CoinSales sell listings.
