Well with all the RPM's of the 1938 Buffalo nickel I couldn't remember what ones I needed to complete the set of all 38 D D rpm's. So I pulled the trigger on these two, and sure enough I have both RPM's the WRPM 002, and WRPM 005 see the images below.... boy someone is going to get a sweet deal. The 002 is in MS -65 PCGS and the 005 is raw nice light copper tone to its skin. The nickel marked RPM 001 is really a 002 tired eyes....
Go to varietyvista.com click on buffalo nickels then rpm & omm for the D/S 1938 D and it will list all.
