JulieAt some point in the long, long past, I said here that the sleeves inside the PSA holders were NOT Mylar. Well, it's true, they are not Mylar in any protective sense, bump-wise. but they are very thin Mylar, called Mylite, which should keep the card safe from it's own plastic holder and anything that got inside of it, toning or yellowing wise...
I bought my Peck and Snyder already sealed in Mylar, as did Jay Miller who sold it to me...
