Thank you very much, pawpawdiv9, that is great some great info! Glad to see a CDN place to send them. Like the idea of that much better! I appreciate it!

P.S. Sorry, but what does, "Value limit $500 per card" mean?

Thats just the value of what the card is worth at the moment. Of course the Mantle is well above that by all means and some others you have shown.
Of course PSA is the much better for re-sale purposes, as they fetch more money and they do have a new security hologram slab.
Its purely your choice, but DO get it slabbed. Like someone said, going to a show might not be all bad..You can get it done while waiting, despite whatever it takes...2hrs or so.
You can kill that easily doing a walk-thru.
SGC is not a bad 2nd choice, some folks like their holders, for the pre-war like of the black gasket i assume. SGC does have good customer service and talk to Earl, he can help ya out if need-be.
