Johnson Matthey was founded in 1817 in London as an assaying and precious metals business, and became one of the most established names in bullion refining over the following century and a half. Its bullion bar business is no longer active in the form collectors know it — Johnson Matthey sold that division, and bars carrying its name stopped being newly produced around the mid-2010s as the company refocused around its industrial and catalytic chemistry businesses. This history matters specifically because it separates Johnson Matthey bars into a closed, finite category rather than an ongoing product line — every bar in circulation today was produced before that exit, not manufactured currently.
Because production stopped, Johnson Matthey bars now function differently in the secondary market than an actively-produced brand like PAMP or Valcambi — supply is fixed rather than continuously replenished, and long-established collector familiarity with the brand has kept demand for existing bars strong. Older Johnson Matthey bars, particularly from earlier production decades with older serial and design conventions, are sought after by some collectors specifically for that vintage/discontinued status rather than purely for their bullion content. As with any discontinued bar brand, buyers should be more attentive to authentication given the fixed supply, since no new legitimate examples are being added to counter-check against.

Start tracking freeNo — Johnson Matthey exited the precious metal bar refining business around the mid-2010s. Every bar carrying its name in the market today was produced before that exit; none are newly manufactured.
Yes — they trade based on their gold content like any bullion bar, and the fact that production has stopped has, if anything, sustained collector interest in older examples rather than diminishing it.
The company sold its precious metals refining division and refocused around its industrial and catalytic chemistry businesses — a corporate strategy shift rather than any issue with the bar product itself.
