Look at this cover. The issue date of a genuine 321 2/18/1908. This cover is postmarked in 1907 before the stamp in a horizontal format before even issued. It seems weird that someone would fake this coil before they were actually issued. OR In my opinion was a 319 taken off the cover and then altered and put back on the cover long time ago to try to deceive a collector long time ago. Note the old "coil"
and "net $75.00" pencil markings. If you look very closely you can see minute traces of perf holes in the upper right corner. Looks like the fakers were at work long long time ago. Any other opinions ?
