VERY FINE AND CHOICE. A FRESH AND OUTSTANDING GUIDE LINE PAIR OF THE RARE 1910 SINGLE-LINE WATERMARK 2-CENT HORIZONTAL COIL, SCOTT 388.
The 2c single-line watermark horizontal coil, Scott 388 was in production for only a short period of time before being superseded by the Perf 8-1/2 issue, Scott 393. In addition, due to the greater popularity of the horizontal coils with users, combined with a wary attitude by many collectors that early coils were simply trimmed stamps, many were used and few preserved.
With 1979 and 2015 P.F. certificates
