Capped bust halves are a study in variety. The lettered edge variety especially piques my interest; I remember my wonder when finding out that they actually included the inscription “Fifty Cents Or Half a Dollar” on this coin (and others, of course). That’s one way to keep the unscrupulous from shaving the edges for precious metal... and also a great way to impart some monetary history.
John Reich designed the capped bust coinage, which was used for 30 years on silver denominations. The lettered edge half dollar went through many facelifts and remodels over the years, including changes to the elements of the edge lettering, but it always remained true to the engraver’s original vision. Many dates are relatively affordable in reasonable grades, though to collect every variety would be a daunting task. The lettered edge transitioned to reeding beginning in 1836
