. I started a local man who was a friend of my parents into insulators 42 years ago and he found some neat insulators over the years. I traded him back then, and I never knew that this was that hard to find error Coolie hat, even back then. We didn't really look at things like this in the early years as most of us collected the colors and shapes. not errors and bubbles, swirls, etc.....Well he died several years ago and now the wife had a local auction and I bought a lot of my traders I traded him back then in 1970..Note that this has some snow and is greenish too. Error date, Patented May 2, 1883, almost looks like 1888...
