I Need Help!

I'm a new member to the society, but about 4 months ago, i started buying Morgan Silver Dollars on Ebay, and got taken to the cleaners a few times, on ungraded NOT CARSON CITY MORGANS!

I paid way more than these coins where worth, but will keep them for my daughter who is 9, and maybe when she is my age, they will be worth alot more?

What i want to know, are graded MS-63, by NGC TONED CARSON CITY MORGANS worth between $300.00 to $400.00 dollars today? They all have a blue NGC seal in the large Presidential Clear case's, and the blue seal is wrapped around the case, making it unopenable i believe? I just want to make informed decisions buying these coins. Thank you, and, if you wish to email me directly you can at sobertwo55@myway.com, or sobertwo@sbcglobal.net
