1 oz Silver Bar – Johnson Matthey – JM: product overview
From assaying to bullion
Johnson Matthey traces its origins to Percival Norton Johnson’s London gold-assaying business in 1817. George Matthey became a partner in 1851, giving the firm the name recognized on these bullion products. This background connects the bar to an established assaying and refining business; it does not date an individual bar or establish its rarity.

Frequently asked questions
Does the Johnson Matthey name identify the bar’s age?
Not by itself. Dating a specific bar requires its format, markings and any supporting records. Treat a manufacturing-date claim separately from the company’s much older founding date.
How should I compare its premium with another bar?
Use the same metal amount and packaging, then compare total delivered cost. A smaller bar can cost more per unit of metal because fabrication and packaging costs are spread over less metal.
What should I record after buying this item?
Keep the invoice with the product name, quantity and any visible certification or serial number. These details help distinguish this offer from other dates, grades or packaging variants.
Does the asking price guarantee a later resale value?
No. A future offer can reflect the metal market, product demand, condition and selling costs. Compare current buy and sell quotations for the same product when evaluating the spread.
