I don't know if treaty Oak acorns are available any more.

In 1989 someone tried to kill the tree with a massive overdose
of herbicide. Parts of the tree were lost, and the part that
survived didn't produce any acorns until 1997. IIRC, they're
still a scarce commodity.

Try the e-mail address at the bottom of this link and see what
they say:
