Addenda Data Sheets for Bill Bugertís Registers
now available for readers


Bill Bugert has published five volumes of his series, A Register of Liberty Seated Half Dollar Varieties, which provide details on all known die marriages for Liberty Seated half dollars.

  • Bugert, Bill. A Register of Liberty Seated Half Dollar Varieties, Volume I, San Francisco Branch Mint. Gettysburg, PA: Self-published, 2009.
  • Bugert, Bill. A Register of Liberty Seated Half Dollar Varieties, Volume II, Carson City Branch Mint. Gettysburg, PA: Self-published, 2010.

  • Bugert, Bill. A Register of Liberty Seated Half Dollar Varieties, Volume IV, New Orleans Branch Mint 1853-O WA to 1861-O. Gettysburg, PA: Self-published, 2013.
  • Bugert, Bill. A Register of Liberty Seated Half Dollar Varieties, Volume V, Philadelphia      Mint 1839 to 1852. Gettysburg, PA: Self-published, 2016.

Since publication, a number of new die marriages have been reported and confirmed, and Bill has written detailed data sheets on each of the new die marriages, so that they can be inserted into the books.

The table below lists the new discoveries. Included are links for each individual data sheet in PDF format. Alternately, you may simply download all data sheets for each mint -- San Francisco, Carson City, New Orleans, and Philadelphia -- as a group. These libraries are compressed Zip files which can be decompressed into their individual PDF files.
