The Tonegawa Collection, of Japanese ownership, was commenced in the late seventies. It has grown to its present state mainly by the acquisition of parts of older collections, the purchase of coins from
dealers and public auctions. Its central and ongoing emphasis is, undoubtedly, the coins of al-Andalus, though some early North African coins have also been included. The collection attempts to cover, as well as has been possible, all the various periods that make up the numismatic history of al-Andalus. However, in some cases, a selective emphasis has had to be made, concentrating resources on finding and acquiring rare or singular coins. This is specially the case of Almoravid dinars, were, for example, the purchase of the more common and plentiful dinars has, usually, been avoided.
Special thanks should go to Fawzan Barrage, Sebastian Gaspariño and Tawfiq Ibrahim for their help and advice in the construction of the present site*.
