Hey, I’ve seen a few greenish notes that seem to hide a “7” in their serials or in the design. They’re usually from a special run or a commemorative edition. The green glow is often a tiny microprint or a holographic strip that only shows up under certain light. If you’re after a limited edition with a “7th‑digit vibe,” look for series that use a seven‑digit serial or have a motif of seven stars or something similar. Those little cues are the designer’s whispers. Oddity coins are like the banknote’s cousins—small, often overlooked, but packed with story. Keep an eye on the fine print and the tiny icons; they’re the breadcrumbs that lead to the full narrative.
