最終年度にCOVID-19の影響で計画の度重なる延期や変更を余儀なくされたものの、研究期間全体を通じて10回にわたり、貨幣流通関係の古文書、出土銭の実物と出土地点、あるいは銭貨流通の拠点遺跡などの現地調査と研究会を開催し、研究組織全体で相互に成果・知見や視点・方法を共有した。本研究の主要メンバーのほぼ全員と、研究会に招いたゲストスピーカーの一部から寄せられた15本の論文を、「中世貨幣の成立と展開」「貨幣をめぐる明と日本」「出土銭からみた貨幣流通」「中世から近世へ」の四部に編成して、中島圭一編『日本の中世貨幣と東アジア』（勉誠出版）として刊行した。
Although the plan had to be repeatedly postponed and changed due to the impact of COVID-19 in the final year of the project, 10 times throughout the entire period were held research meetings and field surveys on ancient documents related to monetary circulation, excavated coins with their excavation sites, and sites that were centers of coinage distribution; the entire research organization shared results, findings, perspectives, and methods with each other. Fifteen papers contributed by almost all of the main members of this study and some of the guest speakers invited to the study groups, organized into four parts ("Establishment and Development of Medieval Coins," "Ming and Japan Concerning Coins," "Money Circulation from the Viewpoint of Excavated Coins," and "From the Middle Ages to the Early Modern Period,"), are published as "Japanese Medieval Coins and East Asia" edited by Keiichi Nakajima.
