I want to say I have some of these, but I honestly don't know for sure. I will have to dig back through my stuff and check to see. There is just something really familiar about it to me. I think I shared a post a long time ago with all the old silver I got from my grandparents, but I don't recall for sure.
You may have just seen the regular one here and there and that's why it looks familiar. I think they were fairly common in the midwest when we were kids, at least they were in Indiana. The Susan B Anthony dollars were more common, but Ikes still showed up here and there.
Anyway, if you find you do have some silver ones, you should do a post!
Thanks, I will have to look into it. That could be it. I feel like I have some thing that is tied to the moon landing, but again, I am not sure. I will have to dig into my stuff again to see.
