I have been thinking about getting some of my vintage graded and am wondering about this 33 Goudey Cochrane. I have had this card since the mid-80s when my dad bought it for me. I hope you can see from the scan that there is a miscoloration on the top right, which looks like a gum stain to me.
My questions: How much does this affect the grade? I have heard of some cleaning methods around here; how would any of you handle this issue?
Thanks in advance.
