1. Age and Origin: The age and origin of the figurine can significantly affect its worth. Older, antique brass figurines tend to be more valuable than newer ones. If you know when and where the figurine was made, it can provide clues about its rarity and value.
2. Material: The purity and quality of the brass used can also impact the value. Higher quality brass, with a higher copper content, is generally more valuable than brass with lower copper content.
3. Design and Detail: The intricacy of the design, the level of detail, and any unique features of the figurine can add to its value. Figurines with fine details, intricate patterns, or historically significant designs may be more valuable.
4. Condition: The overall condition of the figurine, including any damage, wear, or tarnishing, can affect its worth. Well-preserved figurines in excellent condition are more valuable than those with significant damage or wear.
5. Provenance and History: If the figurine has a notable history or provenance, such as being owned by a famous person or coming from a well-known collection, it can add significantly to its value.
6. Market Demand: The demand and popularity of brass eagle figurines can fluctuate. If there is a high demand for such figurines, it can drive up the prices.
To get an accurate estimate of the value of your 4-inch brass eagle figurine, it is recommended to consult with an expert in antique appraisals or collectibles. They can assess the figurine in person or provide an appraisal based on detailed photographs and information.
