While specific dimensions such as diameter and weight are not provided—indicated by the placeholder values of '0.00000000'—this suggests that precise physical attributes are either unknown or not applicable for this particular medal. This piece falls under the category of "Coins" with a sub-type labeled "Coins," indicating its nature as a collectible item rather than a circulating currency. The denomination is categorized as "Other / Varied," which suggests that it does not adhere to standard coinage denominations, further emphasizing its commemorative and collectible purpose. It is noted that the mint responsible for its production is "Unknown," which can sometimes add an element of intrigue for collectors. The coin's production type is classified as "Proof," suggesting that it was struck to a higher standard of quality and finish, typically reserved for special editions, making it more desirable among collectors.

Convention Medal from the United States represents a unique collectible opportunity, characterized by its proof quality and connection to the numismatic community, despite the lack of detailed quantitative specifications.
