The present invention relates to a coin return process applicable in coin returns in which at least two types i of coins of different values coexist in a single storage area. The process has the steps of: obtaining a total value to be returned; assigning different initial weights Weight<SUB>i</SUB><SUP>0 </SUP>to each of the at least two types of coin, i<=2; identifying the coin to be extracted or recovered by the return prior to its extraction or recovery; Weights<SUB>i</SUB>' is equal to a pre-established value, in which case the coin is extracted. Then, modifying, after the identification of, Weight<SUB>i</SUB>' the coin to be extracted or recovered by the return, the weight assigned to the identified coin, where the Weight<SUB>i</SUB>' being the modified weight; and, checking if the modified weight, Weight<SUB>i</SUB>' is equal to a pre-established value, in which case the coin is extracted.
