One of the most visually distinctive machines in the sale, the Jennings Buckaroo stands out with its bright yellow plastic front and playful figural bust design. This four-wheel machine reflects the bold, character-driven aesthetic that defined 1950s slot machine production.
Beyond its striking appearance, the Buckaroo retains key original components, including its back door, cash box, and keys, and is noted to be in working condition. These details are essential for collectors seeking authenticity as well as functionality.

Mills 5 Cent Golden Nugget Royal Gold Slot Machine (ca. 1957)
The Mills Golden Nugget Royal Gold brings a sense of glamour to the lineup. Finished in a gold glitter cabinet, this three-reel machine captures the opulence and showmanship associated with mid-century gaming culture.
Described as “very scarce,” the machine includes its original back door and keys, adding to its desirability. While it shows expected signs of age, it remains in very good overall condition, making it both display-ready and historically significant.
Estimated at $2,500–$3,500, this lot offers collectors an opportunity to acquire a visually striking and less commonly seen Mills model.

Watling 5 Cent Rol-A-Tor Slot Machine (ca. 1940s)
For those drawn to rarity, the Watling Rol-A-Tor is a standout. Produced in far fewer numbers than the more familiar Rol-A-Top machines, this model features a classic cast cornucopia design and a vibrant yellow cabinet.
Referred to as a “collector’s dream,” the machine includes its original back door, keys, and cash box, and remains in working condition. Its scarcity alone makes it an appealing option for more advanced collectors.
With an estimate of $2,000–$4,000, the Rol-A-Tor offers a balance of rarity, condition, and value.

Mills 5 Cent Golden Nugget Slot Machine (ca. 1952)

This example is described as a “very rare original machine” and includes a chrome base along with its original back door, cash box, lock, and keys. It is also in working condition, adding functional appeal to its strong visual design.
Estimated at $2,000–$3,000, this lot presents an excellent opportunity for collectors seeking originality and standout color.
