I haven't collected US since childhood (several decades ago). I no longer collect, but am selling my collection and researching it in the process. I've done a fair amount of writing and sharing of info in the past 20 years. I'm also researching many thousands of cut squares and stamps that someone gathered from businesses in Union City, Indiana, generally in 1891-1893. It was an unusual Scott 231 "broken hat" variety that finally prompted me to join this group.
