Sure, but decimalized American coins also don't relate to their values, excepting the quarter. And multi-pound notes even in pre-decimal Britain were labeled like multi-dollar notes in the US.
This is one of the things that often throws me off when I see American context questions online. Like, I've never really researched it but from what I understand you have at least three coins, right? Pennies are 1c, Nickels are 10c and Quarters are 25c. Oh, and Dimes are... 50c? 5c? I genuinely don't know actually. With the Pound Sterling it's easy. £1 = 100p, and then you have the one pence, the two pence, the five pence, ten pence, twenty pence, fifty pence, one pound, two pounds, five pounds (switching to notes here, although five pound coins exist as legal tender but are rare, usually commemorative), ten pounds, twenty pounds and fifty pounds. All of those are very easy to work out the values of - and they follow a nice neat pattern as well (1, 2 and 5 of each multiple of 10). The only tricky thing might be if people talked about 'coppers' and 'silver' coins - coppers are 1/2p, silvers are 5-50p. Also another nice thing is that the 2p is exactly twice the size (volume wise) of the 1p and the 10p is twice the size of the 5p and in both cases the coins being compared are the same material.
Anyway while I'm on the matter of currency, and since this is random stuff, a friend of mine is a bank teller and thus works with different currencies daily. He handles about a half-dozen different ones with reasonable frequency (and a few others occasionally) and he's said that of those, the only one he dislikes working with is the US Dollar. I forget exactly why he dislikes them but I think two major issues are that it's not as easy to tell the notes apart at a quick glance as with most other currencies (I haven't done extensive research into it but IIRC US notes are all predominantly green with only slight hue changes, and only slight size variation? Most other countries change size and colour much more noticably between note values, making it far easier to tell them apart), and also he said they just feel a lot less pleasant in your fingers. I've never handled USD so I dunno how true that is, but eh.
