The thing I noticed from the start about the open 3 on the ebay coin, was that it had a flat (left) downward projection for the top of the 3, while the real open 3 coin has a "spiked" projection. Also, on the ebay coin, the middle stroke of the 3 points points to below the bottom of the 6, while the real open 3 coin has the middle stroke of the 3 pointing to the middle of the lower half of the 6. I do not believe the ebay coin is a 1863 open 3. jmho...
