A 1955 Proof Franklin Half Dollar graded NGC PF68 is a highly desirable and potentially very valuable coin. Here's a breakdown of the factors contributing to its rarity and potential worth:

Rarity:

• Limited Mintage: Proof coins are not intended for circulation but are specially minted for collectors. The 1955 Proof Franklin Half Dollar has a relatively low mintage compared to business strike coins (coins minted for everyday use).
• Stringent Grading: The NGC PF68 designation signifies an almost perfect condition. Professional grading services like NGC meticulously assess coins, and only those with exceptional qualities (sharp details, full mint luster, and minimal imperfections) receive a PF68 grade. This stringent process ensures the rarity of coins in this top tier.

Factors Affecting Value:

• Specific Variety: There might be subtle die variations within the 1955 Proof Franklin Half Dollar mintage. These can be identified by experienced numismatists, and some varieties are rarer than others, impacting value.
• Eye Appeal: Even within the PF68 grade, there can be slight variations in a coin's surface quality, luster, and strike. A coin with exceptional eye appeal (meaning minimal contact marks or blemishes) might fetch a higher price than one with more noticeable flaws.
• Market Fluctuations: The collectible coin market can fluctuate based on economic trends and overall demand for specific coins.

Value Estimation:

Unfortunately, due to the rarity and subjectivity involved, it's difficult to provide a definitive value without physically examining the coin. However, here's a general range based on auction data:

• NGC PF68: Sales records indicate 1955 Proof Franklin Half Dollars graded NGC PF68 can reach prices in the range of $20,000 and above, with some exceptional specimens exceeding $50,000.

Recommendations:

• Variety Verification: If you have the coin, look for identifying markers to determine its specific variety. Online resources like PCGS CoinFacts ([invalid URL removed]) can be helpful for reference.
