Poor boy only can print a money with one serial number, the pros since except number serial our Luke can print the money with other factor can be replicated identical, at least this guy can bypass a security, and since what I saw is we would like to face an empire that probably involved clockwork-steam-meka like city, even if Luke face place with CCTV-fantasy like security, he can bypass it without anyone notice. Rule of counterfeit, use it only once in one person/store, and then escape safely. And hope this Luke guy know appearance is everything. And one more, trust haha.
