The story
I kept buying cards that were 90% of the way to great.
A scuff on the border. A little surface haze on a holo. Nothing you could do much about, and nothing worth sending anywhere — so it just sat in the binder, a little worse than it should have been.
Just Mint started as me working on my own collection: figuring out what actually helps card stock, what makes it worse, and where the line is. Enough people asked me to look at theirs that it turned into a business.
I work in person, one batch at a time, here in the Twin Cities. I photograph everything before I touch it, I tell you when a card isn't worth the risk, and I'd rather turn work down than hand back something worse than I got it.
