I found an interesting letter where everything looks authentic and correct except the rate that was used. Until the 01.07.1945 the tariff for an ordinary letter was 1 Lire and not 1,50 Lire! It could be that it was simply a mistake of the sender, although there is also the possibility that it was a mistake of the postal staff.
It is important to know some circumstances at that time:
a) In an official circular letter of 26.06.1945 new postal rates were announced and new DFJ dinar was introduced. A tariff for an ordinary letter was set as 1,50 Din.
b) In an official circular letter of 27.06.1945 post offices in the Ljubljana region were instructed that they will have to use stamps of the Ljubljana provisional issue as long as they are not supplied with new federal stamps. The exchange ratio was set as 1 Lire = 1 Din.
So, taking a) and b) plus a general situation of that time with full of changes and turbulence, someone can easily imagine that the mistake could be also done by the postal worker who charged 1.50 Din = 1,50 Lire.
1945 Ljubljana, local provisional issue, letter franked with 1,50 Lire, sent from Ljubljana (27.VI.45) to Samobor. Censored by the military censor in Croatia.
