The first "2 CENTS 2" Wash-frank stamp was #406. However, all the 3 CENTS and higher denominations from the beginning (1908) were in the 2 CENTS 2 format (e.g. 3 CENTS 3; 4 CENTS 4; etc). The ONE CENT and TWO CENTS were the only values typed out as such until 1912.
Does that answer the question or am I still missing it?
