The coin in question is a 1904 Barber Dime, a ten-cent piece minted in San Francisco (designated by the "S" mint mark). As part of the Barber Dime series, this coin features a design by Charles E. Barber, depicting Liberty in a classic, ornate style on the obverse, while the reverse showcases a wreath encircling a large numeral "10," symbolizing its denomination. Made of 90% silver, this dime weighs approximately 2.5 grams and has a diameter of 17.9 millimeters. The 1904 Barber Dime is relatively sought after among collectors, particularly given the total mintage of 800,000, which suggests a limited supply compared to more common years in the Barber series. This coin is representative of early 20th-century American numismatics and serves as a testament to the artistry of coin design during the era. As a collectible, its value can fluctuate based on factors such as condition, demand, and market trends, although coins in excellent condition can command higher premiums.
