The earliest known use of #434, September 23rd, 1915
This eleven cent type was current for a little over a year prior to the use of the unwatermarked paper. It was never used in any great quantity by the public and copies were procurable at Post Offices for quite some time after the new unwatermarked type had become generally current. Thus in spite of the comparatively small number issued this stamp is only a little more desirable than the ten cent stamp, of the same issue, of which more than six times as many were printed.
Consequently used copies are much less common than the 10¢ value.
Because the 11¢ was not widely used blocks are quite scarce, there being no obvious purpose for them. As a result used block of four can sell for between $40 and $60.
#434 was issued with the following plate #'s
