This is significantly lighter than the expected 4g+ for a 25.3mm coin, attributed to casting imperfections (voids, gas bubbles) leading to a rougher metal structure. This variance makes it a rare variant.\u003cbr\u003e\u003cbr\u003e### Features:\u003cbr\u003e\u003cbr\u003e*   **Finishing:** Features sharp edges on the outer rim, sides, and anti-aircraft (likely a mistranslation, referring to the edge finishing) along with polished flat surfaces, indicating a high-quality specimen.\u003cbr\u003e*   **Rarity:** The unique weight, combined with the excellent condition and precise dimensions aligning with the \"small flat coin\" (소평전) standard, makes this a valuable collector's item.
