Postage Due Stamps, Cancelled But Ognh

Some years ago I purchased a small BOB lot, mainly because it had a bunch of US Officials.

The lot also included a number of Postage Dues, including an imprint plate number strip of three J31, pen cancelled, but full original gum, never hinged.

Also included were 5 x 5 blocks of all denominations of the 1931 postage dues. These are no gum, all cancelled "Kansas City MO (129)", and appear to not be postally used either.

Thanks to a page on Riverside Stamps' website, I learned about "receipt use" of postage due stamps, although this explanation doesn't made complete sense to me. Is this explanation correct for how apparently cancelled but postally unused stamps were issued?

And the J31's. Are they considered "used", since cancelled, or mognh, because they weren't postally used and are ognh? Or something else not listed by Scott's Specialized?

Thoughts?

Thanks, Burnside

Yes, they are used. The purpose of stamps is for post office accounting and that was what happened with your postage due stamps. Whether or not they ever got stuck to something was not really the point, the point was the $$$ accounting.

Before burning the remainders; some escaped and were roller cancelled by the local post office in question for collectors.The low values of that era are not worth much.

No, these are not remainders.

Don is fully correct. There are quite a few threads on this site which show large multiples (sheets!) which were roller-canceled as payment receipts for postage due for business reply mail accounts and such. Many of the canceled sheets were not stuck to anything, thus have cancels and yet full gum.

No watermark. Thanks for sharing, and you must have picked that sheet of $5 for the Kansas City, MO cancel. Your cancel has the number 122 in parentheses, while my sheets are all 129. Any significance to that number?
