Incidental Fluctuations or Deliberate Selection? (Three Hoards of Follis Coins of the Last Quarter of VI Century). The article tells that the selection criteria for assemblages of bronze coins of big value were determined, for some of the assemblages, by the societal concepts about worth of the coins produced in a certain, relatively short – three-ten years period. Though each of the periods had its own scale of relation of value of the coin to its weight, the scales were strictly related to each other. In other words, there was a certain general scheme of relations between the value of the coin and its weight, period and place of coinage. All the definitions of the coins, except of Thessalonican coinage before 562, are given in this article according to MIB I, II. A rapidly emerged structure of monetary circulation is related to the same.
