Javier de Hoz (2011, pp. 196–198) considers plausible the internal contextual and combinatorial arguments that would support the hypothesis that these Iberian elements could be interpreted as numerals. In fact, concerning the specific values, he considers valid the proposed equivalences between Iberian with 'one' and between Iberian with 'half', according to the marks of value found in coins, while he considers that the rest of the proposed equivalences are a working hypothesis. Regarding the equivalence between the possible Iberian numerals and the Basque numerals, he agrees with Lakarra (2010) that the shape of the documented Iberian forms does not fit the expected protobasque forms. Finally, he considers that the greatest difficulty in accepting this hypothesis is, paradoxically, its extent and systematic nature, because if it was correct, it would result in a close relationship between Iberian and Basque, which should allow the identification of other relationships between Iberian and Basque subsystems, as clearly as this one, relationships that no investigator using reasonable linguistic arguments has been able to identify.
