The initiators of this series Coin Collection and Coin Hoards in Bulgaria (CCCHBulg), intend to make public the collections of ancient coins from those museums in Bulgaria where they have access and where they can find adherent followers, co-authors, and people who are aware of the importance of 'sealed ' information. The philosophy of the authors and the contributors of this project are based on the understanding that this type of information is not a personal or even a national property in perpetuity, but is above all - a universal possession.
