What is the worth of a perfect condition 1963 Franklin half dollar?

Without more detail on the coin, it is hard to say what the value is. You need to know whether it is a business strike coin or a proof coin. You need to know the mint mark. A 1963 Franklin will have no mint mark or a D mint mark. You need to determine whether the coin would be considered to have Full Bell Lines (the 7 lines at the bottom of the Liberty Bell on the reverse side of the coin). Finally, you need to know the grade or approximate grade of the coin. Coins are graded on a scale of 0 to 70 with 70 being perfect. Coins are classified into mint state coins (coins that were minted to be put into circulation) and proof coins (coins that were minted for collectors). A perfect mint state coin would be an MS70 and a perfect proof coin would be a PF70.

PCGS, one of the most reputable third-party coin grading services, has never graded a Franklin half dollar an MS70 or a PF70. Not to say that the "perfect" Franklin half is not out there, it just has not yet been graded.

A 1963 Franklin half that receives an MS65 grade by PCGS would be worth $50. If the 1963 Franklin half received a MS65 Full Bell Lines, it would be worth $1,400. A 1963 Frankin half that receives a grade of PF68 is worth about $80. Coins that are graded and "slabbed" by a reputable third-party coin grading service are going to be more valuable than raw, ungraded coins. Therefore, to get a true picture of what your coin is worth, you need to find out a little about grading and determine the condition or grade of the coin.
