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 based on when each listing was scanned.
- Premiums are frozen at scan time and are not recalculated using today's spot price.
- Medians are weighted by each listing's total fine-metal content, normalized to troy ounces. Every fine ounce contributes equally, with no per-listing cap.
- These are observed asking premiums, not completed sale prices.
- Product rows include only listings matched to that catalog product, so their samples are a subset of all listings that may describe the product.
- Rows with fewer than five eligible listings are hidden.
- Asks under US$100, numismatic listings, and listings with pricing warnings are excluded.
