A Fair Trade

I marched straight across the kitchen counter holding my green bill, hunting for the morning's best deal! That's when I spotted it: a shiny copper penny resting right under a banana stem. What a color! I slid my green bill down onto the polished stone and grabbed the penny with both hands. It was way heavier than I thought, but I managed to hoist it upright against a giant ceramic mug. One crisp green bill for a heavy copper treasure—total upgrade!
