From my research, commemorative halves are "less collectible," but I have a special fondness for Columbus because my birthday is October 12th and I think it's really cool that there is a Booker T Washington half dollar from over 70 years ago. My mom's family is from Iowa and the McKinley dollar is apparently rather rare. More so posting these for people to enjoy as a thank you for helping me hone my grading skills in my other threads... 1892 Columbian half dollar 1893 Columbian half dollar (this one looks really good in hand) 1946 Booker T Washington half dollar (both of these look pretty great in hand) 1946 S Booker T Washington half dollar 1946 Iowa centennial half dollar...If anyone knows which side is the obverse and which is the reverse, I would appreciate being informed...thanks...there are two of these and they both look good 1917 McKinley gold dollar...this thing is tiny and the only thing from my grandpa in a more substantial case, so the pictures are through the case but still half decent
