Re: A question of lighting when evaluating proofs
Russ, I recently found these nice (huge!) scans you made of a '64 proof. Does the hazy stuff in the fields represent hairlines on these, or is this some kind of mild oxidation type haze. I noticed a decent percentage of proof '64 Kennedy halves has this, some with more of it than others. Would this detract from a higher…
