I can say just common in all respect - nothing that have some "more" on it, and face value are low like need to be when post put hand to poeples pocket, even when it is in humanitarian intention. Both stamp have 10.00 serbian Dinar face value, that are together around 0.40 US$, and dealer will give it maybe 20-30% up of face value.
#5: Like usually at this time, and around this time, Serbian people are again in position (if they want or not - dosn't matter - it is democracy) to support construction of churches around. This one go for Sv. Sava (Vrachar - Belgrade) - not big money in face value, just 0.20 US$ per one, but, if someone in one week need to send 100 mail, it will cost him. Design is "like usually" - nothing more to say.
