Owing to the fact that you specified coins, my entry possibilities are somewhat limited. Looking for strikes that either bear a valuation or were struck for circulation, these are what I can contribute. Not unique but definitely eclectic. Z
Shoot. Youse guys gots some amazing stuff. Ain't gots nuthin' nearly as that. Breathtaking is all I can say!
@Eric the Red I love it, but... the Alamo was 1836, which shows on the Obverse 1836-1936. But, the date on the Reverse is 1934. So, I guess they started a couple of years early? Was 1934 the only year made? Thanks for posting.
They issued them from 1934 through 1938 to raise funds to build the Texas Memorial Museum. Wikipedia has a good description: https://en.wikipedia.org/wiki/Texas_Centennial_half_dollar
