SGC all the way! You will wait a long time but these would pop in SGC holders and the grading price is VERY reasonable. Most of these can be done for $15 per at a value of under $500 each. The Young and Brown will cost you $35 each. I'm thinking if you are good with scissors, try to cut the matte away at the sides. Cutting as close as you can get, the corner mounts might fall off easier. I'm jealous!
Congrats either way!
Peace, Mike
