The second one is a 1919 issue from Bulgaria (or what then was Kingdom of Bulgaria) with a face value of 2 stotinki.
Edit: The Bulgarian Ministry of Transport, IT and Comm. has a catalog of what seems to be all Bulgarian stamps. Unfortunately it's only in Bulgarian, so I'm not sure this link would help you much: http://www.mtitc.government.bg/page...=144&id=1871
Here's what is says about your stamp though: Num. printed: 47085000, in use until 30 June 1923. There were quality problems with the whole issue (paper creasing, partial loss of gum, and perforation problems). The artist of the design is S. Badzhov.
