Hi Christopher,

Thank you for contacting Mearto with your appraisal inquiry.
If this truly does not have any inscriptions or impressions in the bronze, it is almost certainly a posthumous casting of a much smaller size than what typically bring between four and six figures at auction. This is a nice decorative copy and priced accordingly.
Based on the photos and information provided, and subject to examination, this is:

after Frederic Sackrider Remington (1861 - 1909)
"The Rattlesnake"
bronze
12 inches high
CONDITION: appears to be in good condition
$500-800*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
