These are Western/cowboy riding spurs with leather spur straps. They’re definitely older working equipment rather than modern decorative reproductions, based on the heavy steel construction, wear, oxidation, strap construction, and hardware.
From the photos, I’d tentatively date them to roughly 1900–1940, with 1910s–1930s looking quite plausible. Comparable museum examples are often dated to the early-to-mid 20th century, while antique California/Western examples with similar construction can reach back into the late 1800s/early 1900s.
The unusual feature on yours is important: they have very large multi-spoke/star-shaped rowels, a heavy curved heel band with pronounced twisted/ribbed decoration, and old stitched leather straps with braided edging. The leather looks genuinely old and heavily used. I would not clean the rust, polish the steel, oil the leather heavily, or replace anything yet. Original surfaces and straps can matter to collectors.
The maker is the big question. An ordinary unmarked vintage pair can be relatively inexpensive—a comparable vintage pair recently sold for about $60. But identified antique Western makers can be worth hundreds or substantially more: an auction lot containing two identified antique pairs sold for $480, while collectible Kelly Bros. examples have carried estimates over $1,000. High-end maker-marked examples can go into the thousands. eBay
For your pair, as photographed and without finding a maker's mark, I'd initially think approximately $150–$400. If they're an identifiable early maker or an uncommon documented pattern, that estimate could change dramatically—potentially $500–$1,500+ depending on attribution and provenance. I wouldn't sell them for the low end until we check for markings.
The most useful next step is to look for stamped names, initials, numbers, or symbols. Check the inside of both heel bands, both sides of the shank near the rowel, around the strap buttons, rowel hubs, buckles, and backs of the leather straps. Makers such as Kelly Bros., Crockett, North & Judd and others used markings that can substantially affect identification and value. For example, documented Crockett-Renalde spurs carry a CR mark, while Kelly Bros. examples are explicitly maker-marked. River Rat Antiques
