Philatelists Study U.S. Bank Notes
Respected stamp dealer and educator Clark Frazier taught the course which was attended by two dozen philatelists from around the country.
The course dealt with various U.S. stamps which were printed by three different printing companies over a 20-year period during the late 1800s. Also discussed were major changes in paper production technology that occurred during that period which has been a source of major confusion among catalog producers and collectors.
Students learned how to identify different design changes including secret marks and re-engraving, paper types from hard to soft, grills and special printings.
Shown above Clark Frazier (holding stamp) and students examine a U.S. Bank Note paper type.
