Thank you for contacting Mearto with your appraisal inquiry. Based on the photographs and description provided, the subject of this appraisal is a Brooklyn Dodgers baseball cap manufactured by Spalding, circa 1950s. The cap is in good used condition and is blue with a prominent white felt "B".

According to the current owner, the piece was acquired via inheritance. Caps of similar style do not come up for auction in traditional settings unless they are game-worn or autographed; thus the online auction market forms a basis for this appraisal for comparable sales.

In consideration of the factors noted, a Fair Market Value (pre-auction estimate) of this piece would be estimated at $75 to $100.
