Presort/Nonprofit Plate Number Coils (PNCs)

Hello, new member here with a question:

I'm a fairly advanced collector who is getting back to collecting after some time off. I've been accumulating things with the intent of sorting through everything when I have time.

I've saved a lot of clipped stamps from envelopes and I saw the call from Boston 2026 for off-paper stamps, and I've been soaking them to send off a big envelope. Among the things I've found were a fair number of PNCs on commercial, postally processed covers that I received in the mail, dating back to 2003.

My question: I know it's better to keep PNCs on cover when they're tied with a postmark. What about Presort and Nonprofit PNCs that don't have a postmark when used properly? Keep them on cover or soak them?

Thank you for any replies.

I only have a few PNC on cover, and I believe that all of them are uncancelled. If you find one with a cancel, I would keep it on cover.

PNCs with a plate number are always better on cover. If the contents are their as well, keep it as a package.

Why do extra work to destroy value?
Please keep all the PNC's on-cover.

The advantage of presort/non-profit stamps is getting a lower postage rate and elimintaing the need for cancellation. The vast majority of these on cover won't have a cancel, BUT will still be a "proper use" and should be left on cover as postal history. To add, many will have USPS-applied bar codings or other markings which document their transit through the mail stream.

Please keep in mind, PNC's are also available as First Class, Forever, Postcard and even make-up rates

The ones that have the mailer's permit postmarks are both less common and offer proof they were actually used, so
i would keep those intact. As for the others, it depends on what your plans are. Are you looking to keep them four your collection, or do you want to sell them? If you want to sell them, just understand the common ones will be difficult to sell on cover as there are more covers than collectors.

Thanks very much for the replies. I understand the value of PNCs tied to covers with a postmark as postal history. My question was really about Presort/Nonprofit PNCs that are on commercial covers that bear printed return addresses and maybe artwork that don't have postmarks or any other post office processing mark, and so can't be confirmed as processed through the mail. For instance, I actually have an APS envelope with a Nonprofit PNC on it that doesn't have any other processing mark on it. I don't collect covers or postal history, so I'd be looking to sell them.
