Black Spots on WLHs
Was this an issue with the mint's process/silver composition or post mint storage? Looking to upgrade some of my dates and so many MS coins on EBAY have spot issues, either effecting large areas on the coin or a big, noticeable spot on Lady Liberty or the Eagle that is a quick turnoff. So many graded 63 & 64.
Or is this just a selective sample on EBAY with dealers just trying to sell their dreck. Looking at dates from mid 30s to 47.
