I was sorting through a bunch of #167 when I found this one. I've never seen something like that before. Anyone have an idea on the cause of the red line? It's not a coil, so... ?? Thanks for your answers!
As far as value is concerned, it may or may not increase. If it does increase, it will be very minimal because there are so many of these available. Being a definitive stamp, the normal one has a CV of 20 cents and even with the guide-line, it 'might' jump to 25 or 30 cents. Mint would be a little more again.
