The 1955 is the first year in the final run of Elizabeth II threepence. The date is relatively common with a number of
mint rolls and mint rolls surfacing, most of which contained higher grade
mint state coins with the typical mint roll averaging at MS65. Despite
this, the date still commands reasonable premiums in higher grades, somewhat contrary to the numbers available leading me
to conclude the date is somewhat overvalued. Collectors would do well to aim for at least MS66 for this date but in MS67
the coin becomes quite rare with only one coin certified so far
