Block of four used U.S. postage stamps, 20¢ Monticello issue (Scott #1047)

The 20-cent Monticello stamp was issued by the United States Postal Service as part of the Liberty Issue series between 1954 and 1965. This stamp features Thomas Jefferson's iconic Virginia estate, Monticello, which he designed himself and is now a UNESCO World Heritage Site. The Liberty Issue was a long-running definitive series that replaced the Presidential Issue and remained in use for over a decade. This block of four stamps appeals to philatelists who specialize in U.S. definitive issues, Liberty series collectors, and those interested in American architectural or presidential history. Blocks of stamps are particularly valued by collectors as they demonstrate printing variations, plate positions, and postal usage patterns. Such items are sought after in the stamp collecting community for their historical significance and as examples of mid-20th century American postal history.
