Grant Zahajko Auctions will bid farewell to its longtime home in Davenport, Washington with the Sports Cards & Memorabilia, Comic Books, Autographs & Collectibles Auction on Wednesday, August 12, 2026, online and live at the gallery. After that the company will relocate to Mesquite, Nevada this fall.

Grant Zahjkjo Auctions has been located in the city of Davenport since its founding in 2016. According to the press release, the firm was attracted to the city’s small town lifestyle, friendly people, affordability as a startup and its proximity to the international airport, since owners Grant and Gina Zahajko often travel the country, picking up consignments.

But a move to Mesquite made good business sense for several reasons. “It will allow us to reduce operational costs so we can keep our prices competitive for our customers,” said Gina, who oversees the operational side of the business. “A larger community positions us better for the growth we’re experiencing. A larger talent pool combined with better logistics for the company’s in-house shipping department, will allow us to continue delivering five-star customer service.”

“The move will bring us to a closer radius to a larger pool of prospective consignors. It’s also important to note that our day-to-day operations won’t be impacted. Our contact details will remain unchanged,” Grant, who presides over the company’s product side, said.

The company’s new building in Mesquite won’t be ready until fall, and upcoming auction details will be announced on www.gzauctions.com.

Firm dates have not yet been set for the lineup of fall auctions in the new Mesquite location. “I want to convey that each auction will feature specifically curated items from estates and collections from across the country,” Grant said.
