I got this today from a fish bowl filled with non-gaming dice. Could only find the one. It appears to be ivory, but I don't know for sure. You can see the strata lines across the 2-spot side. This repeats on the 5-spot side. The 4 and 3-spot sides also have lines like these, but they are arched and link the lines on the 2 and 5-spot sides. The 6 and 1-spot sides have no lines.

If there was ever any coloring of the "Lincoln" (presumably a hot-stamp) it is now missing. The spots are NOT printed and are recessed. This die measures 17mm (3/4").

Thanks for looking and if you have any insight or information, please feel free to share here!
