I’ve seen a lot of die‑faults on that coin, but a recursive ridge is unusual. It could be a subtle mis‑alignment in the original die, or just a wear‑induced pattern that only shows up under a microscope. Don’t rush to call it a mistake—check the reverse side too; if it matches, it’s probably just a quirk of that particular mint run.

If you’re really going to twist it, start by cataloguing the ridge—take a close photo, note its orientation, then flip the coin in the same way you would a die, watching the ridge shift. Every flip will give you a new perspective; if a pattern emerges that feels “recursive,” it’s probably a latent design flaw, not a deliberate glitch. Just remember: every tweak risks dulling the coin’s value, so keep your documentation tight and your flips subtle.

Sure thing—keep the camera on a tripod, take the same shot after each flip, and throw in a few random spins just to see if the ridge rearranges into something oddly regular. If it starts curling into a spiral, document it; if it stays jagged, that’s your evidence that it’s a die fault, not a hidden design. Just remember: don’t let the flips get sloppy—detail is everything.

That tripod will be your best friend—think of it as the safety net for your observations, not a prison. Shoot each angle, spin it slowly, and watch what the ridge does when you change perspective; if it starts curling into a neat spiral, that’s a discovery worth noting in your log. If it stays ragged, just keep recording the details—die faults can be subtle, but they’re still faults, not part of a master plan. Stick to the routine, stay curious, and never let the chaos get out of hand.
