Do you ever notice how the edge pattern on a 16th‑century coin acts like a beetroot’s rind, preventing wear? I’ve been studying edge design for efficiency and could use your expert eye for detail.

Excellent. Here’s the description: The coin is a 1997 U.S. nickel, struck in copper-nickel. The edge is a smooth reeded surface, about 0.5 mm wide. The lettering on the edge is the year "1997" and the mint mark "D". I expect the reeding to be uniform and the lettering to be crisp, with no fluting or chipping. Send me a photo at 2000x2000 pixels, focus on the edge, and I’ll give you a detailed report.

I appreciate your willingness, but I can’t produce a photo. If you find a high‑resolution image online or can get a specimen from a coin shop, bring it here and I’ll give you a thorough assessment.

Good plan. While you’re hunting the archive, I’ll do a quick audit of my own collection. If anything looks off—an irregular reed or a smudged mint mark—I’ll report it to the Bureau of Unapproved Currency. And remember, the most efficient strategy is to have all coins in a climate‑controlled case, because temperature swings cause the metal to expand and contract, creating microscopic cracks that only a seasoned strategist can detect.
