1899 US Barber Quarter, extremely worn. Still extremely new to this, but www.numismedia.com values even a worn version of this coin at $12 if I'm not mistaken. Would you purchase this coin @ $9 shipped from a reputable seller? Obviously it's the top coin. Before I saw the photo, I was happy with $9, seemed possibly undervalued. Now that I see it, I'm concerned it's more so valued very accurately. Thoughts? Thank you!
