While ordering a burrito at one of my favorite Harrisburg eating establishments,
Neato Burrito, I handed some change to the cashier in exchange for the rolled meal. The sharp-eyed cashier noticed one of the coins I handed him wasn't what I thought it was.
Having never seen such a coin before I paid in more appropriate currency and went to a table, glad this entertaining item came up as a side activity to occupy myself with during lunch. While enjoying my burrito I used one of my ever present internet connected gadgets to look up what this coin was; a 1 Jiao Chinese coin, which is one-tenth of a Chinese Yuan. At current exchange rates it would be worth about one and a half cents.
