Most of us have probably been here before. I once was chatting with a stamp dealer who was examining some classic Canadian stamps, and found what he was hoped was a rare Large Queen on laid paper. He watermarked it (I guess laid paper shows up in a watermark tray), then swore, then pulled out his Bic lighter, struck a flame, and incinerated the stamp! I guess it wasn't on laid paper! I guess the lesson is that just as "No" means "No," "rare" means "rare"!
