A useful value
The letter postage rates had at this time been increased from two cents to three cents per ounce or fraction thereof and this eleven cent stamp came into more general use than its two predecessors, for when added to a two cent stamped envelope it covered both registration and letter rate. Through this new use the eleven cent value became better known by large users of the parcel post service and in fact continued in general use in large quantities even after the letter rate had been reduced to two cents.
Earliest documented use
The earliest documented use of #511a is October 6th, 1923 (shown above)
Precancels
This stamp was commonly precancelled, an example is shown above. In this case the precancel was applied inverted, this does not have any effect on the value.
