What I have here is seven pieces of US State Issued Money. Most is in Shillings in denomination of 5 to 15 shillings. Some is in pence such as 18 pence from New Jersey. There is a New York issue for ten dollars. Most are hand numbered. Five have printed obverse. Two have blank obverse. I can scan obverse if there is any interest in seeing it. No rips. Paper is yellowed with brown edges as can be seen in the photo. I have no reccolection of where I got these, which is kind of odd, since they are so unusual.
Just my opinion, but I think they're just copies. I used to have a set similar to that, printed on artificial parchment paper (glassine). As they all look like they're on the same type of crisp parchment paper, that what forms my opinion.
The set I had once had, had that aged look when new. I think they were a souvenir set that I got at a museum.
