Wow, as someone from the US I always thought the $1 notes were far superior to the equivalent coins in other countries. I dislike having coins in my pocket, but already have a note or 2. Adding a couple more adds negligent space.
(ok, hyperbole, but I've had a few like that)
The US note was printed after 2001, that's a considerable time difference.
Though your $20 notes are usually in excellent condition for some reason compared to the british equivalent.
Yeah, that's how they are, but feeling like they're going to fall apart and actually falling appart are two different things.

$20 bills tend to get picked up at the bank, spent at a merchant, and deposited at a bank. Banks will send worn notes to be retired. Many businesses don't take bills larger than $20, so don't use $20s to make change. It's uncommon to pay vendors and employees in cash, so merchants end up with a surplus of $20s that need to be deposited.
$1 bills are used in change, so they tend to get exchanged frequently. Few consumers will deal with $1s at a bank, and many businesses won't ever deposit them, but may need to make withdrawls in $1s so they can make change. They tend to pass through many hands before they get back to a bank where their condition can be checked.
The sterling pound coin was introduced in 1983. The 60s were pre-decimalisation even.
In mainland US, preference for paper $1s isn't unduly burdensome. As a merchant, deposit the worst of the $1s and use the rest as change, no big deal. As a consumer, if someone doesn't take your grimy, half torn $1, try it a couple more places and then take it to a bank (perhaps even your bank). But it's unsurprising that doesn't really work for El Salvador.
I was recently in El Salvador, which uses the USD as an official currency (alongside BTC lol). Despite using dollars, the $1 coins are used instead of notes almost exclusively for that denomination (mostly presidential dollars and some silver Susan B Anthony dollars). I was curious and did a bit of research, apparently the reason is that because day-to-day transactions are done almost entirely in small amounts of cash the paper notes have a very short lifespan (apparently <1yr) there, while coins will last decades.
