How talented are raccoons with coop latches? Years ago (BC -- before chickens), we had raccoons raiding our bird feeders. Then they disappeared without us really doing anything to repel them. But now, they're back. I'm bringing the bird feeders into the house at night and making sure there is nothing edible for them to get into.
All my doors -- access into the coops, runs, and nesting box -- have hinged hasp latches that are secured with simple carabiners. Is this enough to keep them away from my girls?
To the OP, in answer to your original question, I'd say yes.
Coons have remarkable dexterity, but what they posses even more of is incredible strength with those little hands. When they reach in and grab something, it is incredible what they can do. Rip heads off.....rip wires off.....rib boards off. And that is before they start chewing through what they can't rip apart.......

Last summer I was having a running battle with a big old boar.....who was coming in the barn at night to steal cat foot. He destroyed yet another plastic garbage can.......so replaced that with a metal trash can......and heavy rubber tarp strap I used to hold the lid down lasted 2 days before he chewed through that. It now has a metal screen door spring......held in place with carabiners.....and while it kept him out......he tried pretty hard to push it over. Moved it all over the place. So to put a stop to that, figured out a way to wire an electric fencer to the metal garbage can.....and lit him up. Got a funny video of it. Still comes around to steal cat food, but now leaves the garbage can alone.
So aside from your latches on openings, use sturdy metal wire (never chicken wire) at ground level and fasten it tight. Not light duty staples.......use the heavy fence staples or screws and washers (metal roof or siding screws have washers). They can't pull those out.
