Sorry, I'll admit I unboxed the ones still boxed, since I think toys are meant to be out and played with, not pumped collectible investments.
(I no longer have them, though. I was selling my Concept 2 erg, in preparation for moving house, and the buyer noticed my Matchbox dream collection in a tray on the table, and remarked that her nephew/grandson would love those. She'd just given me several hundred dollars for the rowing machine, and I was moving, so I threw in the Matchbox cars.)
I think you made the right decision.
I don't intend to sell my erg but I'm currently in the process of selling my Hot Wheels collection...I wonder if the buyer will notice my erg and remark how much they too love torturing themselves and would I perhaps sell it to them.
I still have a shoebox or two full of Matchbox cars in the attic.
Also I remember that during my job education as (industrial) tool maker in East Germany our master used to rave about Matchbox cars (and specifically Matchbox, not other brands) and how surprisingly hard it is to build the precision tools needed for creating such fine detail, and how baffled he was that western companies could afford to build such production lines "just for toys" - in that sense, Matchbox was even an effective Cold War propaganda weapon ;)
So add Matchbox cars to Levi's 501s as subversive western imports. :)
Some Soviet exposure to Matchbox might well have been intentional by the West, given that we now know there was energetic and creative propaganda, including the CIA propping up an entire art movement:

Today, spies can just robo-post on their adversaries' social media apps, to neutralize a dozen years of formative education.
In particular, they tended to roll much better than Hot Wheels.
The "axles" were some kind of fine spring steel. The matchbox cars had noticeably less drag than other brands and rolled farther and more straight. The plastic on the wheels was more flexible and smooth.
I do think that some thought went into how these things rolled. Or maybe I am mis-remembering my childhood experiences? I guess I will never find out!
The older history is different.
I was already a Matchbox fan when HotWheels were first introduced: HotWheels invented the "give it a push and it rolls a good distance" type of wheels-on-wire-axles, slick enough that they could make the HotWheels race track with the spinning rubber capstan sending the cars all the way around the track. A Matchbox's wheels would turn, but it would only roll inches if given a push.
Matchbox was getting crushed in the market. Then a year or two later (a long time when you're a kid) they introduced the Matchbox Superfast line which had the same type of wire-sprung wheels, but they still weren't as good at rolling as HotWheels.
but being a child on-the-spectrum I was pretty upset by the whole thing for another reason, because Matchbox cars were realistic reproductions of actual car models (Maserati Ghibli); HotWheels cars were imaginary fantasy cars (Green Goblin or something), and I couldn't stand them, I liked realism and my favorite way to play with them had a lot of parallel parking... but HotWheels were better.
so the end of the story is... I hit puberty
And that suspension allowed them to roll much better anywhere, inclusing outside in the dirt.
Also most Matchbox and Hotwheels ended up with bent axle from use while the suspension of the Majorette [1] would usually limit the risk of bending the axle unless you were crushing it.
On first day usually the Hotwheels would roll best followed by Matchbox then Majorette on perfect surface. After tear and wear[2] it was the exact opposite horder with Hotwheels wheel dragging on the ground and wheel arches with their bent axle, Matchbox dragging mostly on the wheel arches with the axle also bent a little and the Majorette would be mostly unscathed.
Obviously YMMV it really depends if you used them on a mat/carpet, on a table or outside in the dirt and how careless you where. I still have some matchbox and hotwheels in pristine conditions because they were supercars or racing cars and I wouldn't have used them outside in the dirt.
[1] it was really a very simple design with one U shaped steel wire that would act as a spring for all 4 wheels.
[2] hotwheels axle were junk and would bend just by looking at the toy with too much intensity
As a result I inherited a lot of his toys when he grew out of them, such as his car collection (which wasn't all that huge). I bought my own ones in the early '80s and comparing them they weren't even close in quality.
The build quality of the older cars were far superior. The metal was thicker and stronger and any moving elements like the occasional opening door would last a lot longer. Sometimes you'd get a new car that could compete in a distance race down a sloped track, but in general their build quality felt very random.
There was especially one from my brother that was my favourite, I think it was a '76 Chevrolet Corvette in orange. It was extremely solid and ran very well, unfortunately at some point I tried to paint it and that damaged the axles, after which it was never the same.
This is exactly what I've noticed with a little one that loves toy cars. We often end up getting Matchbox because they're cooler and not meant to only rocket down a Hot Wheels track. Hot Wheels are too much fantasy these days, Matchbox is where it's at.
Makes you think will what you build keep the same interface or at least backwards compatibility 50 years from now? Probably not and most wouldn't blame you. But it brought us a lot of joy to take things we bought in target that day and connect them to those old sets.
But also had the glow-in-the-dark fold out Matchbox City in a suitcase.
But Matchbox really sticks out in my mind as the manufacturer of the die-cast Voltron toy that every kid wanted in the mid-1980s -- and only rich kids got; at $60 in 1985 or nearly $175 in today's dollars, that shit's steep. I did end up with the Panosh Place plastic Voltron. It was plastic, and the lions didn't combine in a show-accurate way to form Voltron, but I didn't care, it was Voltron.
These days, we have Transformers from Robosen that transform on their own and respond to voice commands -- so rich kids' Christmases are on a whole 'nother level now.
I used to have a huge collection of them. My mom amazingly kept them around, and now my kids have a huge collection to play. What a present!
It's funny how a random thing can date you so specifically, it seems like their heyday was only from 1987-1994 or so.
I still have a pencil case full of cars and its pretty much the only toy that I've managed to keep. I guess being small helped!
Tootsie Toy, which, originally, were either rough die cast or stamped metal. They were literally just hollow shells of cars with axles, in solid color. They were sold loose in a box next to the penny candy. These cars were small, 1" to 1.5" long. Tootsie Toy, later, really up'd their game. The cars were about twice as big as Matchbox/Hot Wheel.
Next were Matchbox, these were the "replicas". They had the normal sized cars, but they also had some King Sized, I was particularly fascinated by this truck and trailer pipe truck they had.
Then, there were Hot Wheels, which were mostly fantasy cars. Splittin' Image, Red Baron, the surf board truck, Jack Rabbit Special. I swear we had hundreds of feet of Hot Wheels track as a kid. And then they brought out the Sizzlers, electric, rechargeable cars. Those were a lot of fun. Also there were the Hot Wheels Heavyweight and the Chopcycles.
Oh, and I should also mention the Hot Wheel Factory. This was back when the toy companies had no compunction selling toys with open heating elements to children. Here you melted rubber-ish compound into an injection mold system where you'd place bases and wheels into the mold and squeeze molten rubbery plastic to make your own cars.
At the high end were Corgi, those were really nice. I had a very nice ambulance. The cars were hefty. But they were rare, not like Matchbox or Hot Wheels.
Trying to compete with Hot Wheels was Johnny Lightning. Known mostly for their elaborate race sets. Where Hot Wheels had things like the Super Charger (which had a pair of spinning wheels used to shoot cars out one end, very useful for loops), Johnny Lightning had a conveyor system. Kind of like a marble track, with cars.
Dinky had some really nice stuff, but they were very exotic. There was a small toy store near where I lived that had not just those, but another line that was very detailed construction equipment. It was all out of my price range as a kid, though. I was definitely wanting Dinky's Thunderbirds models.
Pah, these small reporters with their small ambitions! Scrooge McDuck didn't have a "pool of cash", he had a whole silo-sized building filled with cash, and the "pool" that he used to swim in was merely the visible surface of it: https://www.duckipedia.de/images/archive/d/d3/20230517100725...
One of those original Matchboxes was the bright red Jaguar XKE, a car I have never fallen out of love with (and managed to re-acquire a few years ago).
