10 oz Platinum Bar Johnson Matthey
10 oz Platinum Bar Johnson Matthey is a fully valuable investment platinum bar weighing 10 oz (311.035 g), manufactured by the renowned refinery Johnson Matthey (United Kingdom) from 999.5/1000 fine platinum - the highest investment-grade platinum purity standard compliant with London Platinum & Palladium Market (LPPM) Good Delivery requirements. Each bar is individually packaged in a certified CertiPAMP/CertiCard blister with a serial number stamped directly on the bar that matches the number on the accompanying assay certificate confirming fineness and weight.
Johnson Matthey is a British chemicals group and one of the most legendary precious metals refineries in the world, operating since 1817 with headquarters in London and main refining facilities in Royston (Hertfordshire). The company was a founding member of the London Platinum & Palladium Market (LPPM) and was the global quality benchmark in platinum trading for decades. JM bars are particularly valued on the US and European markets for their precise workmanship, distinctive hexagonal logo and historic brand reputation.

Authenticity certificate and traceability
Each bar is delivered in an original protective blister with assay certificate, which guarantees the metal's origin and confirms compliance of fineness and weight with the LPPM Good Delivery standard. The serial number stamped directly on the bar matches the number on the Johnson Matthey assay card and allows unambiguous product identification on the secondary market. Opening the blister does not invalidate the certificate, but we recommend keeping the bar in its original packaging for the maximum price on potential resale.
Why invest in platinum?
Platinum is one of the rarest precious metals in the world and at the same time a critical industrial commodity used in automotive catalytic converters (Diesel engines, hydrogen fuel cells), electronics and jewellery. Annual global mine output is approximately 190 tonnes, making platinum about 30 times rarer than gold (data: World Platinum Investment Council, World Gold Council). This natural scarcity, combined with growing demand from hydrogen technologies, creates a unique investment profile - distinct from classical monetary metals such as gold or silver.
Investors building a diversified precious metals portfolio often add platinum as a complement to their gold and silver positions. See also gold bullion bars, silver bullion bars and current precious metals prices.

Frequently asked questions (FAQ)
Is 10 oz Platinum Bar Johnson Matthey an original LPPM investment bar?
Yes. The bar comes directly from manufacturer Johnson Matthey PLC (United Kingdom, since 1817), accredited by the London Platinum & Palladium Market (LPPM) Good Delivery for platinum. Fineness 999.5/1000, mass 10 oz (311.035 g) and serial number are confirmed by an assay certificate included with every bar in a certified blister. GoldInvest24 sources its products exclusively from the authorised distribution channels of the manufacturers.
Why is investment platinum 999.5 fineness and not 999.9 like gold or silver?
The LPPM Good Delivery standard for investment platinum (Pt 1 grade) sets the minimum fineness at 999.5/1000 (i.e. 99.95% pure metal). This results from platinum's metallurgical specifics - achieving higher fineness while maintaining the plasticity required for rolling and minting bars is costly and not justified from an investment standpoint. All major platinum coins worldwide (Maple Leaf, American Eagle, Philharmonic, Kangaroo) also have 999.5 fineness, making it the de facto global standard for the investment platinum market.
Is investment platinum subject to VAT?
Yes. Unlike investment gold (which is VAT-exempt under Council Directive 98/80/EC), investment platinum is subject to standard VAT throughout the European Union — typically 23% in Poland and 19% in Germany. The Council Directive 98/80/EC exemption applies exclusively to gold; platinum and silver are subject to the full VAT rate. For certain imports or under specific dealer schemes, the German differential taxation under § 25a UStG may apply, taxing only the dealer margin. The displayed price already includes VAT and is the final retail price; a VAT invoice is issued with each order.
How does platinum differ from gold and silver as an investment?
Platinum has a fundamentally different investment profile from gold or silver. First, it is about 30 times rarer than gold (annual mine output ~190 tonnes vs ~3,100 tonnes for gold). Second, around 40% of annual demand comes from the automotive sector (Diesel engine catalytic converters and hydrogen fuel cells) - which is why platinum prices respond strongly to industrial cycles and emission regulations. Third, platinum has historically traded both at a premium to gold (until 2014) and at a significant discount (after 2015, in connection with the Dieselgate scandal). This different profile makes platinum a valued component of precious metals portfolio diversification.
Can I sell the bar back to GoldInvest24?
Yes. GoldInvest24 operates an investment platinum buyback at prices linked to the current London Platinum Fix (LPPM quotation, twice daily). The buyback price is influenced by fineness (999.5), weight, packaging condition (original blister with assay certificate), serial number matching the assay card, as well as the current market spread. Bars in undamaged blisters with legible assay cards achieve the highest resale prices - therefore we recommend keeping the product in its intact original form.
