Comparison of Missing Star 7 F-101a with F-101
Comments: During late July 2015, Ken Rubin contacted the author concerning an 1851 New Orleans dime purchased in PCGS AU50 with completely missing Star 7. His concern was that a Chinese counterfeit might be at hand a no 1851-O dimes were known with a missing Star 7. The coin in question was shipped for study. Inspection clearly indicated the Seated dime in question was genuine. The missing Star 7 was the result of a minting error; most likely a greased filled die for a short period of time. The fact that Star 6 and Liberty's facial details are not disturbed is amazing. The foreign material that filled the Star 7 crevice on the die was localized leaving only a faint impression of the star at top most point.
Though the missing Star 7 event is technically an minting error, it is no different that reverse die rotations events and is assigned its own webpage and die suffix for publication purposes.
A second example was reported in August by Ken Rubin after posting his discovery on the LSCC message board. This example is owned by Tom Smith in Long Island, NY.
