I'm new here this is my first post!!
Posted By: TimJ
I have yet to get a card graded,so all the graded cards I have seen are scanned.I didn't realize that what I was seeing in the scans could be an insert.Just as Julie pointed out that there is an insert,an insert of this kind being PH neutral could help buffer the paperstock from succuming to it's own acid content.If you have a PH neutral buffer against a media that has an acid content,it can slow the natural acid degredation of the card itself.Just as a note,my experience as an archival framer,I have actually seen prints with "brown acid related dammage"reversed to an extent by sandwiching the piece for a period of time in PH neutral paper.The acid content will tend to "migrate" to the Ph neutral paper,thus reducing the acidity of the piece.
