That’s awesome! I’ve collected a few coins but none worth that. I only have one ancient coin of the Gallic Emperor Tetricus II that’s in rough condition, but I only purchased it for $10. The only surprising coin I have is an 1809 US Capped Bust Half Dollar that is apparently a rare variant with some markings along the edge, and PCGS says there are only an estimated 900 of that variant that are still around. Unfortunately, there was already a deep scratch on the front when I bought it that likely lowers the value to that of the normal variant, but I still love the history and rarity of it.
