From a quick look, it seems to me the seller has another listing for the exact same group of proof sets:
332097505417This one is a BIN for $899 or make offer.
I also note that both listings use a photo with the old
ebay picture logo in the lower right corner. This means, I think, that the photo was copied from an
ebay listing at some time in the past. It may mean nothing, but I think it is odd. It might mean they have tried to sell this set before, or it could have come from a listing where they BOUGHT it long ago.
The seller has been registered since 1998, has almost 31,000 positive feedback rating with no non-positive in the last year. Toolhaus, however, reveals that they have received quite a few bad feedback in the past for various issues related to coin sales, noticeably proof sets.
