This book focuses on the path of challenges that led to the company’s independence from selling antique coins as a side job, and its 10th anniversary. It also provides an easy-to-understand introduction to the company’s unconventional business development, its experience gained in the field around the world, and the future prospects of the market. While this is a business book, it can also be enjoyed as an introduction to the fascinating world of coins. ■Title “The Coin that Changed My Life” ■Author Information Kosuke Watanabe Born in Fukuoka in 1986. After graduating from the Faculty of Business and Commerce at Keio University, he discovered coins while working for a foreign IT company and began buying and selling them as a side job. In 2015, he founded Antique Coin Galleria Inc., and currently has an office in Toranomon, Minato-ku, Tokyo. He works every day to communicate the appeal of coins—their emotional and cultural value and their asset value—to as many people as possible. ■Book Overview One coin changed my life. From an ordinary office worker, he started selling antique coins as a side job, which led him to independence—and now, 10 years after founding his company. This is a record of the real challenges the author has faced. The author reveals his upbringing, his experiences with the Great East Japan Earthquake while working for a company, his involvement in the smart grid business, and how his side job of selling antique coins dramatically changed his life.
Furthermore, the book details the company’s expansion through unconventional ideas, including inventory-less sales, online shops, and systems utilizing YouTube and social media. It also includes anecdotes that give a firsthand glimpse into the global market, such as winning a bid at an international auction in Monaco and expanding overseas. At the same time, it clearly explains the joys of
collecting, how to watch out for counterfeit coins, and the future prospects of the coin market. While this is a business book, it can also be enjoyed as an introduction to the appeal of coins. “Even an ordinary office worker can carve out a life for themselves by starting a small business that suits them”—a book that will give you the courage to take a step forward in these times of stagnation. ■Book information Price: ¥2,001 (tax included) Order from Amazon here https://www.amazon.co.jp/dp/4903883892/ Publisher: Antique Coin Galleria (2025/11/18) Publisher: Tokyo Kirara Publishing Release Date: 2025/11/18 Language: Japanese Book: ‎ 200 pages ISBN-10 ‏ : ‎ 4903883892 ISBN-13 ‏ : ‎ 978-4903883892 Dimensions: ‎ 18.8 x 12.8 x 1.8 cm Special events will also be held to celebrate the 10th anniversary of Antique Coin Galleria and the release of Watanabe Kosuke’s publication!
