* Condition: Postcards are often judged by their condition. Is it pristine, with no tears, creases, or fading? Or is it worn and damaged?
* Rarity: Some Shirley Temple postcards might be more rare than others, depending on the image, the year it was printed, and the company that produced it.
* Demand: The value of any collectible is ultimately driven by demand. Are there collectors specifically interested in Shirley Temple postcards?
To get an idea of its value, you could:
* Look online: Websites like eBay, Etsy, and specialized postcard websites can give you an idea of prices for similar postcards.
* Contact a postcard expert: There are postcard dealers and appraisers who can give you a professional opinion on its value.
Keep in mind: Just because a postcard has a famous person on it doesn't automatically make it valuable.
