The coin in question is a one-cent piece (1¢) from the Post-1776 Private and Regional Issues series of the United States, dated 1788. Notably, this coin does not have a specified mint, designer, or material, which suggests that it may either be a privately issued piece or one from an obscure regional minting effort that does not fit into standardized categories. It features a diameter and weight that are marked as zero, which might denote either a rarity in surviving examples or that the specific details remain undetermined and may not have been accurately measured or recorded. The absence of a mint mark indicates that it was produced without a specific locational identifier, further hinting at its unique or private origin. With a mintage figure of zero cited, this coin could potentially represent a historical example that might not have been mass-produced or may not have survived through the years, making it a compelling piece for collectors interested in early American currency. Overall, this 1788 coin stands out due to its year of issuance during the formative years of the United States, marking both a time of nascent monetary policy and the early steps towards a unified currency. As a part of its original era, such a coin could carry significant historical and numismatic value, particularly for collectors focusing on early American private coinage.
