That’s what I usually get on the envelopes from stamp sellers: decades old stamps from the “bad investment” portions from stamp collectors.
I contacted the seller and it turned out her husband was a stamp collector and gave her his low value cast-offs to use as postage. I found it amazing that 30+ year old stamps were still valid. It's only recently they've become invalid postage as now stamps require a barcode.
Also I used to get items delivered to my office, and the office manager's husband was a stamp collector, so she used to ask to keep the stamps I got (I used to order electronic components from all over the world) so this completed the philatelist cycle.
Another old currency anecdote. I used to work on the checkouts at a supermarket in Cambridge circa 2009 and at least two times we'd get visiting academics from the USA who had studied in the UK years before and they'd try to pay with currency they'd had from the time, except it was the awesome old pre-decimal money (We switched to decimal in 1971). I found it quaint that they thought it was still valid and thought to bring it with them.
We can't see the full set of "lower denomination" stamps on the letter, but I'm not 100% sure it's actually lower denomination. The sender of the stamps seems to be using the "2 domestic forevers + some amount of cents = 1 global forever" formula. I think the UK sender didn't need to include _two_ global forevers.
From the blog, the letter from California was dated April 2022, at which point the rates were domestic = $0.58 and global = $1.30. So the California sender correctly attached two domestics valued at $1.16 total plus an additional $0.14 to make $1.30.
It would be hard to know that ahead of time though. The global forever stamp is good for letters up to 1oz which can be as little as 4 US letter pages. It took the FSF 5 double-sided pages. Granted, it looks like lightweight paper & the post office doesn't seem to be very picky about this. But I think sending two forever stamps was being on the safe side.

May have been more apt.
Is eBay really anyones first thought when looking for a (non-collector) stamp to (actually) mail?
Perhaps he should have picked up a few £1 coins on eBay, use them to purchase some stamps from the post office?...
I guess the a more "digital native" way would have been to first check if the USPS supports some kind of downloadable/printable stamping method, like QR codes or pre-bought labels (which, according to come early comment, they do).
Wild that so many commenters don't see the satire dripping from the post. Is it just a UK thing to never take things at face value?
