I just had a discussion with my LCS about selling me currency in old PCGS holders. He says it's not a big deal and I responded that the old PCGS holders can no longer be verified and that when one enters the holder's number it brings up a silver coin. In other words the number on the old PCGS currency holder is no longer valid. I pointed out that this could be an issue when reselling. What do you think? Out there in dealer land is there a discount offered on currency residing in old PCGS holders?
