These are pretty special, each in their own way.
The 8888 $1s are printed by the department of the Treasury specifically as good luck notes around Chinese New Years. Its the only special repeating number notes they intentionally make and they're made in a limited series each year.
The 888 $2s are even more special as they're not intentionally made with the 8s for a special purpose - they're just lucky like that. And they're $2s.
These are available as is, caligraphied, fixed with oil, or both.
