As this is an ebay thread it all goes back to if you want something decent / valuable buy it from a dealer.You will eventually come unstuck and any saving you may make on a few will soon be wiped out on the bad one.Ebay serves a purpose and is good for cheap varieties etc but not high value,i use it almost daily ,a few days ago i bought a couple of pennies for £1 without getting out of the chair and does not cost anything to look
