I picked up the following '65 Mantle with the idea of submitting it for grading. I have never submitted anything to be graded yet. To my untrained eye it looks to be in extremely good gradable condition. First, I would like experienced opinions as to whether this would be a good card to submit. If so, should I shell out the money to join PSA to get it graded or submit it to SGC? Right now I don't have enough vintage cards that I would want to submit to PSA to justify the initial costs. Not sure if I will over the course of the next 12 months. Any thoughts are appreciated. Thanks!
