Sorry to bump this, but I got a response from Beckett for those who could be interested:
1. We use USPS Global Express, so there are no customs or duty fees. We insure the order for the amount you specify.
2. You'll want to insure them for the value of the card, not the service.
3. There is no designated place for the minimum grade, so you will just need to write this in the margin next to each card. Make sure to highlight the minimum grades so our invoicing department catches it.
The last question I have, is how can I determine how well my SP Authentic, and Ice cards are centered? I find it hard without any sort of border...so how is centered judged on these types of cards?
Any tips are appreciated 
Thanks!
