I thought I was finally getting a “deal” on a classic U.S. airmail lot. The scans looked sharp—crisp cancel, clean color, and centering that felt almost too good.
But when the envelope hit my desk, the stamp looked a little “too neat” along the edge. Not torn—just oddly even. I’ve learned that my eyes can lie faster than my heart.
I dug out my perforation gauge, the one I usually grab only when I’m feeling cautious. Still, I measured left and right… and then stopped, because the numbers didn’t behave the way they should. One side lined up like it belonged, while the other looked off by a fraction that suddenly felt huge.
I held it under bright light and checked the holes closer. The spacing looked consistent in a way that made my stomach drop—like someone had tried to correct a problem I couldn’t see from the front.
So I did what I should’ve done earlier: measured all four sides, compared to a reference, and planned the next step… but I’m not sharing it yet.
Because after I cross-checked the margins, I realized the mystery wasn’t just the perforations. It was what the perf was trying to hide… and what it might mean for my next bid.
