Dear all, I also have some bisected stamps in my drawers, just took them out and scanned for this occasion - to share with you.

This is a bisect from Italy (kingdom period end of 1800's / beginning of 1900's), #65 in Sassone. 1 centesimo stamp cut in half to form even 10 centesimi together with a 2 centesimo stamp and the post card of 7½ centesimi for foreign postage (which has been cut in two pieces and does not show the 7½ centesimi print). Postmarked Roma 2. Aug. 1900.

Three examples of Warsaw Municipal (local) post bisected to form the rate for printed matter (this has been also displayed in another thread here recently), so not so much about that anymore - for more info see:

Three examples of bisected 2 cent coiled dragon stamp of the Chinese Empire, from 1906. These are Changsa uses. Evidently the post office had run out of the 1 cent stamp and used bisected 2 cent stamps in the absence.

An Israeli bisected definitive issue from 1949. The address has almost faded, but it seems to have actually been delivered = postal usage. Don't know much about this.


There was a Bolivian bisect also earlier in this thread, however on that occasion it was suspected to be a favor cancel for philatelists, in these cases it is probable that here we have an actual use for posting documents by a bank and a mining company. Indeed in the mining company cover there is an arrival postmark of Santiago (in Chile). As a note: It's really sad to get these "identity" protectors to spoil the items...

Austrian bisected stamp, a rather obvious favor cancel of a 1 kreuzer stamp to reach the postal rate of 2½ kreuzer. OR then this is one of those post cards sold to tourists that were pre cancelled for tourist use outside or even inside a post office. This one was never sent. Postmark Rochlitz 3.1.1900.
Examples of unused bisected stamps from Portugese India - I think from the early 1900's. The bisection is done with a perforation. Hard to tell by just looking at them if they are "real". Don't know much about these.

A well known Finnish bisect by the stamp merchant Lauri Peltonen in the advent of the coming occupation of the Hanko area in the South of Finland in the middle of the WWII, after the winter war when Finland had to cede the area to the Soviet Union. Bisect of the 4 FIM model 1930 definitive issue stamp depicting the head post office in Helsinki. Post mark Hangö 20.III.1940. The "Sista posten från Hangö" (in Swedish) means translated "last post from Hanko" (before the occupation). This one actually went to Sweden, so some of these "fabrications" were actually used in posting letters. The "story" goes so that Lauri Peltonen bought all the stamps from the local post office to make this happen. These sell for 10-15 euro each, so don't pay more

Hope these are of interest!
Cheers,
Mikael
