Donley Auctions offers Lionel, MTH and brass trains in online sale
Lionel, MTH, brass and HO equipment anchored Larry Prosken's online-only sale, with Key Imports, KTM and Overland pieces drawing layout builders and brass collectors.

Donley Auctions put the Larry Prosken collection on the market as an online-only sale with a very broad hobby footprint: Lionel, MTH, Weaver and American Flyer on one side, and brass locomotives on the other. Bidding closed the morning of Thursday, June 18, 2026, while Donley kept adding items daily, a sign that this was one of those catalogs worth checking more than once.
The sale was centered in Huntley, Illinois, with items located at Donley’s facility in Union, Illinois, and the model-railroad section spoke directly to three different corners of the hobby. O gauge, S track and HO scale were all represented, which made the auction interesting not just for tinplate and toy-train collectors, but also for operators building active layouts. The train material included familiar names such as Lionel, MTH, Weaver and American Flyer, a lineup that usually brings together buyers looking for postwar nostalgia, modern-ready equipment and display pieces all at once.

The brass end of the catalog was the part most likely to draw hard competition. Additional listings identified brass locomotives from Key Imports, KTM and Overland, names that tend to matter when a collector is hunting for precision builds or a missing road name to finish a roster. That same train section was also said to include trackside buildings, rolling stock and layout accessories, which makes the sale more than a straight roster chase. For layout builders, pieces like those can solve an operating scene faster than buying new, especially when they match a preferred era or railroad.

EstateSales.NET highlighted specific train lots that sharpened the picture even further, including Lionel Century Club, MTH Premier Big Boys, Weaver and K-Line. Those are the kinds of names that tell buyers this was not a thin mixed estate, but a catalog with enough depth to reward both top-end collectors and people looking for strong runners or display-grade pieces. The broader auction also carried pressed steel and cast iron toys from Tonka, Buddy L, Structo, Wyandotte, Smith Miller and Arcade, plus military models and pop-culture figures, which widened the bidder pool beyond railfans alone.

That mix is exactly what made the Larry Prosken sale worth watching: a brass section for serious collectors, O gauge and S for tinplate fans, HO for operators, and enough related toy material to keep the room moving. Donley followed it immediately with a separate online-only Relics of the American West auction on June 19, a reminder that this was part of a packed June calendar built to keep specialty buyers coming back.
