Ah, the bronze edge sings. A hidden grid on a mint press? If the die makers had a secret game, they'd make a fuss. More likely it’s a subtle press pattern, an intentional flourish that slips past the eye of a casual collector. The key is to compare the pattern across the lot—if it repeats, it’s deliberate. If it’s a single coin, probably a mis‑pressed strike. Keep an eye; sometimes the smallest irregularity tells the grandest story.
