It's sort of a balancing act between what you paid for the cards and what the chances are that something is wrong here. First off, many here will tell you that the cards they bought in the 60's and 70's definitely showed occasional variance in sizing, so it is definitely not out of the question that those cards were born that way. But you have to decide whether or not a full 1/16 of an inch is sketchy or not. That is a significant difference. You've already stated that you have no reason to either believe the seller or not believe the seller, so you have to ask yourself a few pertinent questions:

1. Do the edges under magnification look as they should? Is there a way to take pics of your 10X magnification and post them here for some of the guys to look at?

2. How do the prices paid stack up? Did you get the cards on the cheap, or can you get the same cards/conditions for close to or at the same prices elsewhere? If it's the latter, then you may be saving yourself a lot of heartache by just returning them now and putting it all behind you. If they were low priced, but there's a possibility of them being deemed 'wrong' in the future, you have to decide whether the amount paid makes keeping them a non-issue.

3. Do you plan on getting the cards graded? If you shelled out a lot of money for them and they eventually come back as ungradeable due to sizing, you are going to scream like a banshee!!! I know what I'm talking about. In Bobby's last group sub, I had 4 cards returned unsuitable (N6: MINIMUM SIZE REQUIREMENT), three 1971's (including a Nolan Ryan!) and a 1961 Babe's 60th Homer. All were measured out beforehand and examined closely while laying atop a modern card, and they were the perfect size, yet I still got screwed...with no explanation from PSA, of course.
