This refers to a United States Bicentennial Eisenhower dollar coin, specifically a Type 1 variety produced in 1976. The coin commemorates both the bicentennial of the United States Declaration of Independence (1776-1976) and President Dwight D. Eisenhower. The inclusion of “authentic” suggests an emphasis on verifying its genuineness, while “brilliant” indicates a high level of surface luster and preservation. “BA17-00040-007” most likely refers to an internal identification or tracking code, potentially used by a grading service, seller, or collector.
These coins hold historical significance as they were issued during a major national celebration. Well-preserved examples are sought after by collectors, with factors such as mint mark, condition, and certification influencing their value. The bicentennial design, featuring the Liberty Bell superimposed on the moon, adds to its collectibility.
