1946 Cuba 5 Centavos: Not Listed In My Old Krause Book

I'm wondering about this coin. It appears to be a copper-nickel Cuba 5 centavo piece of the same design as illustrated in my old (1978) Krause catalog. However, the catalog shows that coin only issued in 1915, 1916, and 1920 (Y# 5). There is no listing for a 1946. Later pieces were struck in brass, for 1969, 1971, and 1972 (Y# 28). Is the catalog listing incomplete or is this 1946 piece something unusual?

Thanks for your input!
