Does Anyone Save Stamped Covers From Your Daily Mail?

I have been doing this for years - saving every bit of mail that arrives at my home mailbox that has any kind of postage stamp affixed. Most of these envelopes are ultimately stored in shoeboxes without being catalogued or mounted in any kind of album.
Since letter-writing these days is all but dead, most of what arrives is advertising mail with the most recent bulk mailing stamps affixed.
Of course, at Christmas time, I receive a handful of mail from friends and relatives with the year's Christmas stamps attached.
Once in a blue moon, someone will send a letter with an actual commemorative stamp, but these are extremely rare.
One thing that I keep a close watch for is any regular definitive coil stamp on a mailed letter that bears a plate number. I'm happy to report that I have encountered a number of these over the years.
I also treasure stamped covers that bear a slogan cancel. Again, these largely appear around the Holidays.
I was just curious if anyone else here collects similar items.

When I was buying on ebay from overseas sellers, I kept a few covers, mostly one from each country. Just an interesting thing to have I think

Yes. Today's mail is tomorrow's postal history.

I have even seen 1st class envelopes I have sent being sold on ebay for over $25 dollars. Priority and Express for even more.

I don't read the Daily Mail. More of a Guardian reader, myself.

What is daily mail? Who gets daily mail? Who gets daily mail with stamps on it?

I have no idea why, but I do not throw away stamped mail. I throw it onto a pile and do not do anything with it.

This topic made me think for a moment about how I receive virtually zero letter mail. Still lots of "junk" mail but nobody writes me a letter and attaches a stamp. Kind of an eye-opener as to what postal services are facing in the modern era. It also points out the cynical aspect of these services continuing to issue vast amounts of different stamp designs annually. I do believe that modern stamps could have some value in the future because of all of this but that depends upon the number of collectors line ascending while the number of mailed letters descends. It is the ascending part that is unquantifiable.

Reidar Tvedt saved his stamped covers. It seems anyone writing to him made sure to pimp the envelope.

If you have kept mail you received since at least 1958, you have been at it for at least! 66 1/2 years!!!

This seems like just saving the part of throwing things away for your children after you're dead. Don't save things your kids won't want, and they won't want your old mail.

APS use to sell the envelopes that people sent in stamps to get authenticated. A lot of high dollar covers. I bought a few lots many years ago. not sure if they do that anymore.

parcelpostguy's reply is by far the best and most relevant here.

Every era of mail has hidden rate, franking, and handing/mishandling gems. Many of these are not fully recognized, understood, or appreciated until much later - when it is too late to influence the supply. Only in recent decades have the Prexie and Liberty series come into their own and unusual pieces appreciated, both in a philatelic and financial sense. Many of these are non-1st class items. This often means junk mail and oversized mail, which have very low survival rates.

The only way to have today's mail for future collectors is for somone to save it. No I don't save everything, but I salt-away enough hoping that the next generation of collectors will mine some treasures from it many years from now.

All someone needs is some cheap warehouse space, and then they can become the Nicholson Baker of the American envelope.

Hardly. Even saving a papercase or two of selected interesting modern covers every year takes a long time to fill a modest closet.

That's because you have taste and discrimination. In a world where people collect and store vast quantities of junk wax baseball cards, there may be some hero who's quietly stashing thousands of used envelopes.

It's called hoarding.
