Mexico 100,000 pesos pattern N # 69483 N # 451573 DUPLICATION

I believe there is a duplication here.  Photos are duplicated.  I think only one entry - N#451573 (copper) is accurate.  

The pictures are indeed duplicated but both pages have a different PL# reference number. So we must assume both versions exist. Maybe someone has that catalog and show the pictures of the bronze and copper coins?: “Las Pruebas de la Moneda Mexicana del Siglo XX”
