Got out my 1993 Scott catalog, and checked the Italian stamps.
The green 25 centesimi stamp is Italian Social Republic #32, issued December 6, 1944. The 1993 catalog value is given at minimum value of $0.15. An used copy's value was a slightly higher $0.22. Given the date of issue, and the political situation of the period, I can't imagine too many saw postal use.
The brownish, 10 centesimi stamp with the inscription "RECAPITO AUTORIZZATO" ("Authorized Delivery") is Italy #EY82, issued in 1930. Again, the 1993 catalog gives the minimum $0.15 value for these stamps. Scott explains their use as follows:
Quote:
"For the payment of a special tax for the authorized delivery of correspondence privately instead of through the post office."
The violet 50 centesimi stamp inscribed "SEGNATASSE" is a postage due stamp, Scott #J47, issued in 1945-46. And again the value is the 1993 catalog's minimum of $0.15.
