What to check on your 1951-S

  • Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 1951-D (9.5 million made).
  • Don't clean it. Cleaning leaves fine scratches and an unnatural shine that collectors avoid.
  • Proof or circulation strike? A proof has mirror-like fields and frosted design details and was sold to collectors, not released in change. The 1951 Franklin Half Dollar Proof (57,500 made) is the one to compare with.
  • Judge the grade under good light. The lower bell lines are the key: Full Bell Lines coins sell for several times the price of ordinary ones.

Circulated examples are usually traded for their silver content. Pick out the best ones: original luster and attractive toning lift a coin above melt, while cleaned coins lose most of their collector value.

The story of the 1951-S

San Francisco hadn't struck the Franklin Half Dollar since 1949. When it came back in 1951, it made 13,696,000. In 1952 the figure was 5.5 million.

1951-D came to 9.5 million and 1951 came to 17 million, so neither mint's 1951 coin is much scarcer than the other.

Of the 5 Franklin Half Dollars San Francisco struck between 1949 and 1954, none was made in bigger numbers. The scarcest San Francisco issue is the 1949-S at 3,744,000. Within the 1950s it's 15th smallest of 22, between the 1954 (13 million) and the 1951 (17 million).

San Francisco coins and the 1955 Bugs Bunny (1951 to 1955)

Output rose sharply from 1951, with Denver passing 25 million in 1952 and 1954. San Francisco struck halves every year through 1954. Those S coins are often weakly struck, so full bell line examples are rare. The 1953 Philadelphia issue is low at 2,796,920. Proof sales climbed every year of the period.

In 1955 only Philadelphia struck halves, just 2,876,381. Many 1955 coins show the Bugs Bunny clashed die, where marks from the eagle's wings on the reverse die left lines in front of Franklin's mouth that resemble buck teeth. Despite the low mintage, the 1955 was widely saved in rolls, so uncirculated examples are easy to find. The 1954-S was the last Franklin half from San Francisco. Many collectors assemble these dates from original mint sets of the period.

How to recognize it

John Sinnock's portrait shows Benjamin Franklin facing right with LIBERTY above, IN GOD WE TRUST below and the date to the right. The reverse shows the Liberty Bell, crack included, with a small eagle to the right. The mint mark is above the bell's beam. Collectors look for "full bell lines", where the horizontal lines at the bottom of the bell are complete.
