you are right, No.1 is the most valuable (except, possibly, No.0, but 0 is at this time not for sale).
logically - it is also the most expensive - its price not known until the entire Issue (edition) is produced and distributed.

so, how can you acquire one?
well, you can make a bid, and reserve it by putting down a payment.
we will remain in touch, letting you know how the Issue is running down and the price climbing. if it is becoming too expensive at any point, just settle for the lowest number still available.
does this work for you?
