Found passport near City Market, Charleston

I found a passport this afternoon around 4:15pm in the Charleston City Market area, along East Bay Street near the Market entrance. It's a navy blue US passport with the gold crest, a slight bend along the lower-right corner, and a faint coffee ring on the back cover. I held onto it for a bit, hoping the owner would return, but no one claimed it as I wandered toward King Street. If you're the owner, please reach out so I can help get it back—I know this can be stressful and it's really important to have it returned.
