hit 21m

A patient just showed me a note, I entered it anonymously. It belongs to 21mdb, entered 25 days earlier in a local casino. Did you win?

Cool! Does your patient know you're into collecting, or were they just asking what kind of crazy person goes around stamping money? :-)

He knows I collect currency. He found the stamp an oddity and asked my advice.

That was a nice thing to do for 21.
Now you know what my stamp looks like!
