How the price, history and dealer offers are measured
Availability comes from our Costco.com scans. A stock window begins when we record the product in stock and ends when we record it out of stock; start and end times are when our checks confirmed the change, so each can trail Costco.com by a few minutes. A price change inside a window is drawn on the chart as a step and is not counted as a new restock; windows more than a minute apart are counted separately, and listings Costco sells as variants of this product are counted together. Some of the oldest windows come from an earlier version of this tracker. Gaps on the chart have no recorded online price. While the product is sold out online but stocked in at least one warehouse, the lighter line carries the last recorded online price forward, for up to 72 hours, until the next recorded price; it is not the warehouse price.
Gold spot is the daily average of recorded quotes by UTC date, scaled to this product’s weight; other dates on this page are Eastern. Premium recorded at the last sellout, against spot at that time. Historical prices are observations, not an offer to buy at that price. Typical time in stock is the median of completed stock windows and is stated once 5 have been recorded; premiums are measured against spot at the moment they were recorded.
Buy-back offers are the prices bullion dealers publish for this product, shown after each dealer’s own fee; an offer can be up to about 15 minutes old by the time it appears here. Shipping, insurance and payment costs are not deducted, and an offer is not final until the dealer confirms a sale. Dealer names are in the member view.
