About Us
NextExchange (NX) is an independent South African collectibles business, specializing in the sourcing and selling of rare coins, bullion, medals, vintage silverware, and historical memorabilia.
NX operates its own Bobshop store and travels regularly to towns and cities across the country, meeting directly with the public to buy quality items and offer instant cash deals.
We collaborate closely with Henk van Zyl, professional numismatist and founder of Vintage Vault. With over 8 years of full-time experience, Henk runs one of the largest and most active Bobshop stores in the collectibles space, consistently maintaining 2,000+ live listings and handling over 1,000 sales each month.
While Vintage Vault focuses on high-volume online trading, NextExchange leads the sourcing and acquisition side, connecting directly with communities, discovering hidden treasures, and bringing them to market.
What We Do
"better, faster, easier"
Mobile Gold & Silver Buying
We bring the scale, testing gear and live-spot pricing to you, whether you’re in Parys, Potchefstroom, Klerksdorp, Carletonville or Fochville. From Krugerrands to broken chains, we weigh, test and pay on the spot so you never have to ship valuables or queue at a pawnshop.
Numismatic & Coin Collectable Valuations
Our heart is in numismatics. We identify rarities, grade condition and price everything from Union pounds to off-metal strikes at fair collector premiums, not just melt value. Complimentary advice helps you understand exactly what you own (and why it matters).
Antiques, Militaria & Curios Acquisition
Pocket-knives, bayonets, medals, sterling tea sets, Art-Deco pocket-watches, if it has craftsmanship and a story, we’re interested. We research provenance on the spot and offer respectable cash or EFT, turning forgotten heirlooms into welcome liquidity.
Estate & Collection Liquidation Support
Clearing an attic or executing a will? We streamline the process with discreet on-site assessments, itemised offers and immediate settlement. Portable scales and XRF testers ensure every gram and hallmark is verified right in front of you.
National Exposure via Bob Shop
Select high-character pieces receive extra visibility through our curated Bob Shop storefront, reaching serious collectors nationwide while you still enjoy local, face-to-face service. It’s the best of both worlds: personal attention plus a bigger market.
What Our Customers Say
Joubert arrived with his testing kit, explained every step, and paid us on the spot. It felt less like selling gold and more like having a friendly expert unlock hidden value in our drawer. We left with cash in hand and complete confidence in the price.
— Sue-Anne & Rudi Botha, Potchefstroom
Professional, honest and totally upfront, no hidden fees, no pressure. Joubert quoted live bullion prices, verified my Krugerrand in front of me and settled the deal in minutes. I’ll be calling NextExchange first whenever I have collectibles to move.
— Cols Horton, Klerksdorp
I inherited a box of English coins and had no idea what they were worth. Joubert separated the numismatic pieces from the silver weight, gave me a clear breakdown and transferred payment instantly. Fast, fair and refreshingly transparent.
— Daryl Matthee, Fochville
