Wow that was a tricky one! I never would've guessed it was 1899 haha Congrats bonbonbelly!!! And thanks for the contest lonegunlawyer!!
The math was a bit off in the last clue, but it is technically a penny and not a cent. Same thing in the U.S., we have cents, not pennies.
Thank you everyone for playing. I am thinking of another "What's lonegun got in his front left pocket?"
