Ok here is what it looks like:
Seller has 3 Massachusetts colonials. You do not necessarily need to be an expert to own coins and to sell them.
The one at 11K is probably a Ryder 13-I (the only reason I know that is because this same coin is being discussed in a different thread), which is a very important variety.
The other one with a picture of the reverse of the 13-I looks to be a little mistake of his. I kindly emailed him telling him of the mistake.
