This coin is a piece of miscellaneous medallic, token, and fantasy coinage from the United States, produced in the year 1977. It belongs to a series that does not have a specific denomination or associated currency amount, indicating it may be more of a commemorative or novelty item rather than a standard circulating coin. The coin is made of silver and was created using the mint strike production method, which generally implies a higher quality finish. However, specific measurements such as width, height, diameter, and weight are not provided, suggesting that this coin's physical attributes may not be typical or easily quantified—possibly due to its design or status as a fantasy or medallic piece. Additionally, this coin does not have a mint mark, which is common for certain types of novelty or non-standard coins. The total mintage is listed as zero, which could indicate that it was never officially produced for circulation, or that it simply holds more value as a collectible. Overall, this piece is likely intended for collectors and may be of interest to those who appreciate historical or unique items related to the United States' currency evolution. Given its characteristics, this coin falls under the category of a non-standard issued item, potentially holding value primarily from its novelty or collector's appeal rather than its material composition or circulation history.
