You approach a stall in the market. "Look at this magnificent gold collar I'm wearing!" exclaims the merchant. "Your chain is so small compared to the gold I already have."
Try something else to trade:
Large bag plain M&M's® chocolate candies
Two US dimes, a US quarter, and four US pennies
Brand new US five-dollar bill
Song lyrics you wrote on the back of a napkin
