“景德元宝小字母钱” likely refers to a variant of the Jingde Yuanbao coin with small-sized or fine script characters, possibly with special marks or from a minor mint. While not an official term, it reflects the diversity and complexity of Song Dynasty coinage. Its historical context ties closely to the peaceful yet economically evolving era of Emperor Zhenzong, and such coins are valued by collectors for their craftsmanship and rarity.
