Any coin collectors on board?

If you are going to keep it and pass it down to your kids then it is worth getting graded. All Morgans in mint state are sought after and like you said if you go on eBay and look at the prices for that coin some MS 65 1880 S coins that have allready been graded are up for as little as $200 on go up to $500+ If you are just looking to sell it and make some money on it I would not get it graded I would just take it to a real coin shop and ask the owner to take a look at it and see if he thinks it is a MS 65 or not. Then put it up for sale on eBay.
