Ron Guth: Included among the varieties of 1828 Half Cents is the very unusual 12 Stars variety. Normally, Half Cents of this type bear 13 stars on the obverse (one for each of the original 13 colonies). However, on one obverse, the engraver accidentally left off one of the stars! The 12 Stars variety is relatively common in circulated grades, but commands a slight premium because of the unusual variety. Mint State examples are scarce, especially with any traces of mint luster. All of the examples certified so far by PCGS have the Brown designation and none has been graded above MS65.
