GEC is not a trustworthy company, and unfortunately that isn't a 67. *I believe MS67 is actually the lowest grade GEC gives for Morgans, just to show their standards.
I will give it the benefit of the doubt and assume it is a genuine Morgan dollar, which means it is worth at least $14-$15 for the bullion content. As far as the grade is concerned, it might be MS or might be AU.
But you didn't consider the fact that your 87 hasn't been dipped to the point of having no luster at all. Chris
There is that possibility Chris; however, the OP's image is a scan and hard to tell if that's the case.
One other thing I think is worth mentioning is that you should not be using the Red Book for pricing information. You will get a better idea of its value by searching auction archives or referring to the CDN Greysheet. Needless to say, never, never buy slabbed coins unless they are from the top tier services. These third-world and self-slabbed coins are overgraded and usually problem coins. I still think this one has been overdipped and worth nothing more than melt. Chris
Regardless of what we, think look at the rarity of this coin and consider that one can be found in beautiful condition at minimal cost as many of the Morgan years can be. Not judging any of the coins posted just remember that regardless the MS grade look at the coin as 100 coins may make the grade but less than half of those will have eye appeal and only a quarter of those will be both struck well and have eye appeal.IMO
