While the ordinary 1943 Steel Cents are seldom worth big money, the rarely seen 1943 Bronze Cents always create a stir and command hefty prices when they are offered at public auction. Technically, these are error coins, created by mistakes at the various Mints, but they are listed in the major references as well. The errors occurred at all three producing mints when 1943 cent dies struck coins on bronze planchets which were leftover from the previous year.
The circumstances under which the 1943 Bronze Cents were created are vague at best. Some say that they were created by Mint workers under suspicious circumstances, like many of the 19th century rarities that are not fully original; others say they are legitimate errors which miraculously escaped the quality control of the Mint in wartime. It is very interesting to note that virtually all examples of the error are well circulated.
The finest known examples graded by PCGS are respectively MS-61RB (Philadelphia), MS-64BN (Denver) and AU-58BN (San Francisco). NGC has graded a single Mint State example of the 1943-S Bronze Cent as well. Offerings of these error coins are few and far between. Select recent auction results include $218,500 for a Philadelphia example graded AU-58BN by PCGS and $212,750 for a Denver example graded MS-64BN by PCGS. In 2012, the finest known San Francisco example graded PCGS MS62BN sold privately for $1 million.
Needless to say, even a well circulated specimen attracts considerable attention, and sells for strong five figure prices at any major auction.
