They have carried these in the past, but I can see that there are 2 newer versions that I need to get. Here are some images of the original 2 versions, and one has been dissected to show the printed label. While not really visible in pictures, these images are printed in a manner that the dollar symbols and denominations are raised, i.e., the opposite of incuse.

When sold at the gift shop, they were $7 each. My thanks to Ron Gaudette for these customized airtites that protect the raised ink.
