Pretty decent obverse for a Blue Ike. Reverse has damage on the bottom. Not sure if I should return this one; the dealer said he'd take it back and give me another. 1. Is this a lamination error? Defective die? Defective planchet? Strike through? Something else? Notice the rim is fine. (Pretty sure it is NOT PMD). 2. Should I keep it or return it? (Cool error or knocked down a peg because it is damaged?) Please be honest.
