There are so many red flags on this auction and the seller that my eyeballs have turned red. Besides the lousy feedback and the questionably "certified" MS-66, the seller has "private" for bidders, has claimed that the coins are "unsearched" (yeah, and I'm selling that bridge that has so much history), and that each group of coins has a minimum "book value" (whose book?). His glorious images obfuscate what he is actually selling by only showing the highest quality coins. I'd definitely bet the farm that almost every coin in every lot is junk, worth little or nothing more than melt.
Don't run away from this guy. Flee on wings!
