Precancel 400A Or Not?

I came across this US stamps which appears to be 400A and a pre-cancel for San Francisco. I cannot find a value for the stamps in Scott catalog so it must be listed elsewhere. It has a hinge but OG and probably fine quality.

yes, it is a precancel - I have the same on the 1c 97 & 2c 398 (also OG NH)

these are listed in the Precancel Stamp Society Classics 2A catalog, it is
known as L-12 E, cv is 15 $, but usually sells for less

"cv is 15 $"
But is that for a used example or unused with gum

Hello everyone;
I too have a 400a I believe .
I would also like to share it with this group .
I think has a interesting cancel not a perfect stamp with the cut off perf but I thought it would be appropriate to share .
I too haven't seen any information on this stamp in pricing in the Scott's catalog
Just on the on cover stamps with the expo machine cover.
Thanks Dan

The Scott U.S. Specialized catalog is only a semi-specialized catalog, despite the title. That is the value for organizations like the Precancel Stamp Society and the International Machine Cancel Society and their extensive literature which goes far beyond Scott.

In the case of the partial slogan cancel, see William J. Bomar's "Postal Markings of United States Exposition", which lists on-cover values for these. Yours is an advertising slogan and *not* an "exposition station" cancel as listed in Scott. It has no particular premium as a soaked-off single.

eyeonwall - us precancel people don't care much about the back - so hinged, NH, NG will not matter to these (on modern Bureau prints there is some interest in NH). Precancelled with gum is still considered a used stamp.

Thank you John and Chasa;
That is great information to know.
