Method: premium % = price ÷ (spot × 1 oz) − 1, using the spot recorded with each snapshot. Prices are single-unit prices as read from each dealer in that refresh; prices our sanity checks rejected are not included. Recording started October 15, 2026, so this page grows with every hourly refresh. See methodology and operating record for gaps in the refresh schedule.
