Coins in Mario Kart make a pretty substantial difference. The speed difference between someone with 0 coins and someone with 10 coins is pretty huge. I typically won’t go too far out of my way for coins, but will try and pick up 10 by the end of the first lap.
In battle mode they can determine what place you get at the end of the match.
If you fall into a pit and have coins, Lakitu will put you a bit ahead instead of behind.
My argument is always, what scrub can’t get the bare minimum? My niece could pull that off at 5 on the switch version. My mom could do it on the original. Both totally filthy casuals.
I have arthritis and I can manage it.
Freaking noobs ;)

Also, “the original”, you mean Mario Kart on SNES?
If you have all 10 they make a good difference. Since all players will choose fast vehicles, having a little boost can often make a difference in a head to head situation.
