    Looks more like dip residue that wasn't properly rinsed and is turning in the holders.

    Best way to resolve it? Send the $1000+ ones to PCGS for conservation?

    They need to be re-dipped in a diluted strength dip and rinsed properly. The problem is once it gets to the stage of the 1934 and 1944 with the old dip residue being acidic it etches the surfaces as it eats into it. That being said those two might be beyond conservation without still ending up showing trace evidence. The 1935 & 1939 should conserve well as they haven't yet turned to the point of no return.

    May be worth sending for professional conservation - if possible. So many coins are damaged by attempts to improve/conserve by those who have little or no experience. The professionals at the TPG are the best resource. Cheers, RickO
