First Strike UNC Submission Question

I just saw on another thread that opened boxes are OK as long as they are received by 13 Jan. That much I understand. But what about unopened boxes, submitted subsequent to 13 Jan., which have a shipping date prior to Jan 13 on the label?
Can they get First Strike at ANY time down the road, as long as the box is unopened?
Thanks.

"First Strike" or "10th Anniversary" designations POSTMARKED NO LATER THAN Jan 13!
$10 extra per label for each coin.
In other words, PCGS is only offering First Strike & 10th Anniversary labels for the W PLATINUM UNCIRCS.
After that, you can only get them labeled with the standard PCGS label.
This member asked PCGS Customer Service. Answer:
<< <i>I spoke with a CSR about an hour ago and the FS™ or 10th Anniv. choice applies only to the MS W-Plats. I ask specifically about the fractional MS W-Golds, and she said they would not offer either for the those gold coins. >>
