i'm planning on going to money show of the southwest (houston) in december. do grading services offer on-site grading at coin shows? i have a mexican coin i would like graded......wondering what my odds are of getting it done
anyone done this? how long does it take?
i've googled some - seems that ngc does some US coins at select shows. don't know about pcgs or the other graders
thanks for any help/advice
