Chamberlain, South Dakota sits where Interstate 90 crosses the Missouri River, a natural stopping point for cross-state travelers, and just off Exit 263, one block north of the local McDonald’s at 122 S. Main, Old West Trading Post has been drawing in road-trippers and regional collectors since it opened in 1998. The shop built its identity around genuine Old West and Native American material: spurs, bits, saddles, and other tack and horse gear alongside Native American items, a specialty that fits naturally with Chamberlain’s location near the Crow Creek and Lower Brule reservations and the broader history of the Missouri River corridor.
Beyond that Old West core, Old West Trading Post has assembled what it describes as the region’s largest selection of South Dakota and regional history books along with a substantial children’s book collection, an unusual specialty for an antique shop and one that sets it apart from the sports memorabilia and glassware focus of most competitors. The shop rounds out its inventory with sports cards and sports memorabilia, primitives, antique toys, vintage clothing, old advertising signs, and paper ephemera, plus a case of new Sterling Silver jewelry set with turquoise, Black Hills Gold pieces, beadwork made by local artisans, and South Dakota souvenirs for travelers looking to bring home something tied specifically to the state.
The shop’s operating hours reflect a business in transition: after more than two decades on Main Street, the owners are moving toward retirement and now keep the doors open largely by chance or by appointment. Visitors are encouraged to check the shop’s Facebook page for posted weekend and holiday hours, or to call ahead at 605-734-0770 or the owner’s cell at 605-680-1831 to confirm the shop will be staffed before making a special trip. That shift toward appointment-based access has pushed more of the business online, and Old West Trading Post now lists merchandise through Etsy and eBay as well as Forever, a photo-keepsake marketplace, giving collectors around the country access to the same Old West and regional history material that used to be found only by walking in off I-90. The shop ships nationwide, so a Native American beadwork piece, a set of old spurs, or a hard-to-find regional history title can reach a buyer well outside South Dakota.
What makes Old West Trading Post distinctive among Missouri River antique stops is precisely that combination of hard goods and books: shops built around tack, western wear, and Native American items are common across South Dakota, but pairing that with what the owners call the largest regional history and children’s book selection in the area is a genuinely unusual pairing, one that draws in local teachers, genealogists, and history buffs alongside the usual antique and collectibles crowd. Chamberlain’s Main Street itself offers a handful of other shops within easy walking distance, so a stop at Old West Trading Post fits naturally into a broader afternoon of browsing for travelers taking a break from the interstate.
Because hours are no longer fixed, anyone planning a special visit, especially one timed around a road trip through central South Dakota, should call ahead rather than assume the shop will be open, and should feel free to ask about specific inventory since availability shifts with each sale. For collectors of authentic western tack and Native American items, regional history and children’s books, sports memorabilia, or Black Hills Gold and turquoise jewelry, Old West Trading Post in Chamberlain remains a genuine, single-owner alternative to the larger antique malls found elsewhere in the state, one built on nearly three decades of specialization rather than broad, rotating booth inventory.
Old West Trading Post in Chamberlain, South Dakota is a Main Street antique shop open since 1998 that pairs authentic Old West tack and Native American items with the region’s largest selection of local history and children’s books, plus sports memorabilia and Black Hills Gold jewelry, now available primarily by appointment or online through Etsy and eBay.
