There are not many gold coins priced at less than $5,000 that can be described, without threat of contradiction, as "rarest date of the type from the New Orleans mint." The 1847-O is one of these and it is the single rarest Liberty Head half eagle from this mint. The present example is evenly worn and problem-free with nice light green-gold color and a complete lack of problems. The 1847-O is actually a rarer coin than issues like the 1861-C and 1861-D half eagle but it is still priced at a very affordable level. I recently listed a nice PCGS VF35 example of the 1847-O half eagle and it received multiple orders within hours of being posted on my website. If you missed that coin and are still in the market for a nice 1847-O, this may be the last shot you get for some time.
