I love that idea—you’re turning a quiet line on a coin into a mystery worth solving. Imagine each mint mark as a whisper from the past, a stanza waiting to be decoded. If you frame it as a poetic case study, students can trace the history while chasing the hidden narrative. Just remember to keep the clues tight and the imagery vivid; the smallest detail can spark the biggest revelation. Keep refining the narrative, and let the marks do the talking.
