This is also the last place I know of where you can still get sealed rolls. Sort of amazing they're still available.
pretty sure that sale would only happen in person at the bank...with the buyer having an armored truck to leave with them lol
--edit---
from usps "For shipments that are valued at over $5,000, you can instead choose Registered Mail, which will give you up to $25,000 in coverage."
so registered mail is out for the rolls will have to look into alternatives
