Theres theres things like 1st ed super rare dark hole and 1st ed Ultra Rare Monster Reborn from Legend Of Blue eyes being worth a lot mint, because you cant find them anymore, all you can find is unlimited, and if you do find first ed they will be damaged most of the time. As well as things like Solemn Judgment from MRD, so yea it matters in those cases. As well as things like Dark Armed from Phantom darkness, where unlimited currently goes for about 30, while 1st eds go for about double than that, depending on who you talk too.
Also, id buy a certain card for more if its 1st ed. Like as a vendor, I pick up 1st ed Tour Guides for about 10 dollars more than unlimited. You can easily make money back on that and people will always want first ed
