NGC Certification 5880656-015. We note at the time of writing that this is the highest grade assigned an example of S.1950 for this mint mark at NGC out of 23 examples graded, and is therefore top of the population at both grading services, as PCGS have only graded one example a level below at 62. The obverse legend translates as "Edward by the Grace of God, King of England, Lord of Ireland" and on the reverse "But Jesus, passing through the midst of them, went His way" taken from the Bible. The accounts of gold output for the period of time where the crown mint mark appears alone are missing.
