Abstract: The gold and precious metal buying machine and method has a housing, a vault and inboard processing stations for: weighing, detecting constituent elements with x-rays and measuring volume based upon gas or fluid displacement. Weight, elemental data and volume is used to calculate gold weight and discounted market value based upon exchange rate, gold weight and a discount factor. Market value is displayed and if accepted, the system generates payment instruction and vault storage command. A rejection negates the acceptance upon request or error signal and generates rejection command. Machine transports item to various stations and, upon the storage command to the vault, and upon rejection to the item return port in the housing. An air displacement test uses a processor measuring a differential volume and a chambered item at a different pressure by a differential position of a piston movable in the chamber.

Abstract: The machine or method buys gold or precious metal items. A housing with a vault is linked to a central office for tracking buy/no-buy sales events and uploading current exchange rate data. The item is placed on a platform leading to processing stations which weigh, image, assay and convey the item to the vault (buy) or return-route (no-buy). User display commands and offers-to-buy, capture user images, scan identity and biometric data and permit user-keyed input. A computer processor calculates a discounted market value based upon exchange rate, weight, assayed purity and discounts. A compiler stores seller's data including seller responses, images and scanner data and buy/no-buy data. An acceptance module initiates a credit event and delivers the item to the vault. A rejection module negates acceptance upon user command or if an error in gold purity, weight, discounted market value or size.
