I have this listed on eBay as well. I was about to send it in to PCGS thinking a slab would help it sell, but someone bought it... then returned it. Turned out they were buying it to flip it and their buyer backed out. If it doesn't sell in a few weeks, I'll submit it for grading.
It's a nice, original Hudson - toned in browns and greens. There's some rub on the high point of the sails, I believe it is an AU-58 coin.
Listed at $665 on eBay, I would take $600 here (PayPal goods and services is great). Free Priority Shipping with signature confirmation (domestic only).
