Obviously a search by 2018 PSA and 2018 BGS on EBAY isn't perfect but it produces an interesting result. A lot of key word spamming happens and more so with people from other grading companies using PSA so certainly not to be taken at 100% but clearly suggesting that with new cards PSA is very much in the hunt. Perhaps winning in submissions. It is obviously no secret with older cards PSA has a near monopoly on fresh cards being submitted so a huge difference in market share. A few months back I was reading about wait times with BGS and saw that as a potentially healthy sign for overall grading submissions but this is clearly a capital issue and really egregious to sit on customers money for a year and climbing. Not good.
