Spink Books has been supplying and publishing numismatic reference works to collectors for over 100 years. The acquisition of the Seaby imprint in 1996 further strengthened their reputation as the worldwide leader in this field. Many Spink titles have become the definitive reference works used by collectors, dealers and auctioneers worldwide, including its annual Coins of England catalogue, Roman Coins and Their Values and other classics by David R.
