Something in mint condition is as good as new. A shiny new mint condition coin should be easy to spot - and surely will always give pleasure: humans do like shiny things!
(These coins are from the 1400s, but still look in mint condition to me.)
Perhaps this is why in Britain something that's mint is something that's excellent.
And even on a Monday morning, you should have no problem at all spotting one of those.
