I would have to agree with Dave about it might be a scam but his reserve has been met so somebody is going to own the lot. Some thing for thought, if the seller has no knowledge of strikes how would he have decided to put a stike in a Yellow Cap and where would he have found a Yellow Cap ? Then again he might be somebody with knowledge of stikes and made a Yellow Cap like some of the collectors have done (dying a clear cap). One thing for certain he has no feedback and is new to ebay thois would and should be a red flag.
