Consider this listing in Grey Flannel's current auction:
https://www.greyflannelauctions.com/...-LOT49740.aspx
The jersey is described as graded MEARS A10. It also has a Photo-Match grade of 8+. And when this shirt was graded, those were probably justified grades. However, look at the pictures of the shirt now. It has serious staining on the collar, front and back. So, is this shirt still an A10, or an 8+, and should it be described as such?
