Some info on Maya replicas

Replicas of tablets etc. are available in the town of Palenque, and other Maya
sites, including Chichen Itza.  There's a whole slew of carvers in the town
of Palenque, of quite variable quality.  It used to be you could visit with
them directly and view a wide selection of pieces.  Now, middle men have
taken over the trade, and direct sales are hard to come by.  The good
pieces go to middelmen for export; the mediocre pieces stay for the local
tourist trade.

None of those images would be more than $200 bought retail in Palenque
today.  If they have an arrangement with the artisan, their price should be
lower than that.  Most of the pieces for sale are made by
tracing from a xerox onto the limestone, then "carving" it with a dremel
using a variety of tools.  The result depends on the skill of the artisan.
Some result in very flat carvings, and some manage to make them seem more
like the originals.  Glyphs can be mangled or quite accurately recarved.
Clothing elements can get reinterpreted, simplified, or be reproduced
accurately.  Aztec and Mixtec art is starting to appear; and around Chichen
Itza, they're carving the local limestone.

My favorite Palenque piece was carved into a slate-grey limestone that
wasn't used by the maya, but is less fragile and thicker pieces can be
carved, so you get more relief.
