Coahoma County, MS: what NOAA's tornado record says

Put another way: Coahoma County sees more tornado activity than 56% of US counties. Mississippi has 82 counties in this dataset; Coahoma County ranks 63 of them by frequency.
Beyond the frequency band: violent history

The dollar figure Coahoma County's rating leads to
Mississippi's Mississippi Emergency Management Agency's Safe Room Program is the number that matters for a Coahoma County homeowner: 75% of an approved shelter, capped at $3,500, cutting the typical $2,890-$13,280 national range to about $722.5-$9,780 net.
What a direct hit isn't required for
Power loss after a tornado outbreak in Mississippi often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
Wind damage may need its own endorsement
Mississippi is one of a handful of states where insurers can write wind/hail damage out of a standard homeowners policy - tornado damage may not be fully covered without a separate wind endorsement. Worth confirming directly on a Coahoma County policy rather than assuming it is included.
What this number is, and is not
One caveat before relying on Coahoma County's number: it is county-wide, and it covers about 553 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. Coahoma County has about 20,105 residents.
