I am taking some time today to browse through my shiny and dust my shelves . Sorry about that gross dust in the picture . I opened this cigar box to find 2 of my zombie coin plastic flaps had cracked open and started to tone . I guess I didn ' t realize this was a possibility , I thought air tight cases were just preference . Do the plastic flaps just dry out and crack ? The box hasn ' t been moved in months . Do silverbugs typically put their 1 oz rounds in protective casings ? What can I do to prevent this from happening in the future ? <| sep |> I think religious reasons were the origin To stop the sensitivitynice feelings you get from it that you mentioned and then it became a cultural thing .
