"So refreshing to finally witness one of the world's leading numismatic experts freely and openly share his extensive research, knowledge and understanding in the creation of this comprehensive, informative and groundbreaking work of reference on Cromwell and Commonwealth coinage.  It is both defining and essential. The bar has been set and it's
set very high!" – HistoryinCoins.com
