The rarest 4004s are the grey trace with a black dot, instead of the gold dot for pin
one.
I have two grey trace but with gold dot. I believe these are older than the grey trace
with black dot.
Although, as originally sold, the 4004 was a Harvard architecture, it could be made to
be, easily, made to be a von Neumann machine with either a 4008/4009 set or a 4289.
I don't know if that was ever done, other than for the Mod 4 development machine.
The 4004 had no interrupt but the later 4040 did.
