The coin in question is from the United States of America, minted in 1818 at the Philadelphia Mint. It belongs to the Early - Post-Declaration series, which encompasses a period of significant historical importance in American numismatics. This particular piece is categorized under the designation of "Other / Varied" for its denomination, indicating it may not conform to standard coinage types typically used during that era. Unfortunately, due to the properties indicated for this coin, both the diameter and weight are listed as '0.00000000', suggesting either incomplete data or perhaps a conceptual representation rather than an actual physical coin. Moreover, the mintage figure is marked as '0', which might imply it was never produced or recorded for circulation, making it potentially a unique or unpublished issue. As a coin categorized as a mint strike, it was created with the intention of being a definitive piece of currency. Despite the absence of tangible measurements or a recorded mintage, the historical significance and the context of its time adds allure, particularly to collectors and historians fascinated by the post-Declaration era of American coinage. Without specific details on size or weight, evaluating its physical attributes or monetary value is challenging. However, its classification and historical context may appeal to those seeking to understand the evolution of American coinage during a pivotal time in U.S. history when the nation was solidifying its identity and economy.
