They're probably just "replicas" going off of Joseph Smith's description. As far as I know, no one ever found indigenous tablets of this kind, so it was probably something he made up entirely.
I responded to a commenter like you in PMs, except they just made it super duper clear that they were exmormons. The people in my area definitely believe that the tablets are real, however I also live in one of the only areas in the US that has a distinct flavor of Mormonism.
With what other people have said in this thread, I assume the tablets around here are something that the Mormons stole to keep the ruse up.
