How .925 works

A price ticker for the secondary market. No selling, no authentication — just the numbers.

1. 1
   We track 40 models.

   Rings, chains, bracelets, eyewear and apparel — silver and gold tracked as separate series.
2. 2
   Twice-weekly snapshots.

   Public asking prices from resale marketplaces — deduplicated by seller, junk and suspicious lowball listings filtered out, gold variants routed to their own series, top 1% trimmed.
3. 3
   Median, not average.

   Every number shows its sample size (n). Fresh listings (first seen within 28 days) are preferred; when a model's fresh sample is thin we say so. The CH-40 index is the equal-weighted ratio of every model's median to its 2026-W36 baseline, ×1,000.
