The 1955 Franklin Silver Half Dollar is an important and highly collectible coin, especially noted for being the lowest mintage year of the series, with under 2.5 million pieces struck exclusively at the Philadelphia Mint. The coin features a portrait of Benjamin Franklin on the obverse, designed by John R. Sinnock, and the Liberty Bell on the reverse, symbolizing American independence. Composed of 90% silver and 10% copper, the coin weighs 12.5 grams and has a diameter of 30.6 mm.

The designation PCGS MS65 FBL (Full Bell Lines) indicates a Mint State coin graded at 65 by the Professional Coin Grading Service, and it shows the highly sought-after Full Bell Lines on the reverse, where the horizontal lines on the Liberty Bell’s bottom are fully visible and uninterrupted. This detail significantly increases the coin’s desirability and value among collectors.

This particular coin is described as having mega monster toning with vivid green, black, and purple colors achieved through liquid nitrogen enhancement. Liquid nitrogen toning is a modern process used to induce intense, vibrant hues for striking aesthetic appeal, creating a visually dramatic effect far beyond natural toning.

1955 Franklin Half Dollars with MS65 FBL grades typically command strong premiums due to scarcity, quality, and collector demand. The addition of spectacular toning, especially with bright, eye-catching colors achieved through innovative techniques, can further boost its market attractiveness and value.
