From the storm reports

Narratives as filed with the NOAA Storm Events Database (public records; lightly trimmed for length).

May 11, 2001 · 0.75″ (penny)

A slow moving cold front drifted south across southeast Michigan. Most of the area stayed cloudy and cool during the day. The exception was near the Ohio border, where ample sunshine pushed temperatures to near 80. A number of thunderstorms developed ahead of the cold front, but only near the Ohio border were the storms able to (barely) reach severe levels.

April 7, 2001 · 0.75″ (penny)

A few thunderstorms developed along the Lake Erie shoreline late in the afternoon. One of these produced penny sized hail in Luna Pier, just before moving out over the lake.

The climb across decades is largely a reporting story: spotter networks, radar, and digital filing pulled far more storms into the record after the 1990s.
