The late Philip Grierson (1910–2006), historian and professor of numismatics at Cambridge University (from 1971), wrote a short essay called The Origins of Money (London, 1977). The monograph is very short (only 33 pages of main text), but it has become something of a classic. Grierson, of course, to some extent relied on the findings of earlier literature, especially anthropologists like A. H. Quiggin (1949) and Dalton (1965), and economists with a knowledge of the anthropological literature like Einzig (1948 and 1949).Read it at Social Democracy for the 21st Century
