Pattern issues from the Casa da Moeda in this period were produced as part of Portugal's gradual rationalization of its coinage system under the Estado Novo regime — a process that involved testing new alloys and denominations years before any public release. The 2.50 Escudos denomination itself had a complicated path to circulation, with multiple pattern compositions evaluated before the final circulating type was settled.
The Gomes reference places this firmly within a documented but sparsely catalogued series. Only a handful of confirmed specimens are known to researchers.
