This coin is a one-dollar piece from the Hawaii series, minted in Philadelphia. It features a unique design that captures the historical significance of Hawaii, though the designer is listed as not applicable. The year referenced on the coin is particularly interesting, as it displays (189193), which appears to be an error or misrepresentation, potentially relating to a specific commemorative context rather than a standard year of minting. As a proof coin, it is crafted with enhanced quality standards, resulting in a mirror-like finish and sharp details, making it a desirable piece for collectors. The coin is made of silver, adding to its value both as a collector's item and for its metal content. However, it is noted that the mintage is recorded as zero, which could imply that it is not in circulation or that it was produced as a special issue without an official release. The dimensions and weight are not specified, which may suggest this particular coin is either a prototype or has been misclassified in terms of its physical characteristics. Additionally, there is no mint mark, indicating it was produced without a designated identifier typically used to indicate the minting facility. In summary, this Hawaii one-dollar proof coin represents a unique collectible with potential historical significance, although its specifics regarding year and mintage appear to be in need of clarification.
