Here are 3 sets of notes I found unusual.
1)

2)
3)
1) I assume these have nothing to do with the Vatican as an issuer but are Italian trade vouchers, like number 3, which I found one of on Numista Exonumia. 2) Closest things to Sammarinese bank notes. These may be the UNC catch of the day. I'm not sure of value so I would like comments. A Japanese seller on eBay was offering them at US $45 each, shipping additional. They are in the banknote catalogue on Numista. 3) Italian trade vouchers of which I found one in Numista Exonumia. I assume the 2 with overprint for CAMPIONE are for use at the Albano Gambetta Co. in the Italian exclave and the one without overprint in Cento, Italy. Note that all 3 have "BUONO" misspelled "BOUNO" on the reverse.What do you think? Did I get a good deal? There is maybe one more trade voucher for a numismatic show in Rome and the rest are real mini-checks, some with identical dates and denominations but different payees. In the Numista Banknotes we seem to distinguish by denomination and bank for type and then list by date and payee.
