Fair assessment. I can only guarantee the scarcity of the 20 that I know of.

But no risk no reward, and you can make an offer at any amount.

They are serialized but it is USPS specific not as 1-20.

You cannot custom print stamps with large photos like this product on the stamp anymore.

Limited edition collectors item. Offers can be made here:
