Wow, friends! I can't begin to express my gratitude for sharing your expertise. I've learned much reading through your comments. Though I'm disappointed that it isn't a more valuable coin, this saved me some headache.
@Sandon I especially thank you for gentle teaching towards finding the right coin. It wasn't clear to me there were so many different variations!
After looking at the variations in the link @EagleRJO provided, I'm fairly certain it's in fact an 1812 O-109a. The upturned 1's are the tell. I think @Just Bob could be correct about 1812 O-103, but 109a seems to match closer to my eye... Might I be on the right track?
