For the chinese 8 is a significant digit,
it sounds just like "Fa" which is chinese for wealth or/and prosperity.
So chinese will go a long way for 8's - licence plates, address, floor in an apartment..
OTOH they will avoid 4 - Si, rhymes with the chinese word for die/death
so they will avoid 4's - same places.
Related example:
In Jakarta, although Indonesian/Muslim country the Chinese
(having all of the money) built many of the taller buildings
… many do not have a 4th or 13th floor. 3A, 12B…
or just skipped altogether.
So yeah, banknotes with rows of 8's - not priced for the US collector
but for the chinese.
