Thanks-I appreciate the replies! These are items that cannot be copied (they come from the earth), and as such have a high collector value.
I've gotten more information from the buyer, and am going to start with a smaller order, paid for in advance via wire transfer. If that goes OK, we'll fill the rest of the order (one at a time to start with).
