First, please excuse me if this was already asked. I searched the topics and couldn't find anything in specific for ASE packaging. My question is: I have mixed type purchase packing from Apmex and other vendors on ASEs, such as the celo wrapper style packaging per coin and also the hard plastic sleeves. I understand the sleeves can emit pvc which can damage the coin over time, but is it okay to leave the ASEs in the celo wrapper unopened to preserve the quality and proof of packing for resale in the future? I understand ASEs are only bullion, but I have seen coins in the original unopened packaging fetch a little more of a premium than those loose. Thanks!
