if 30 luger (aka 7.65mm) with germany stamps; they would be exports to the USA and not bring backs (very unlikley
)
Otherwise looks like nice guns.
for valuation, need better pictures, need to know if completly matching (not magazine) etc.
A rough value is $600-$800 for the 30 lugers and $700-$1200 for the military ones. Also depends on if there are holsters, tools, written provinance, extra magazines, etc.
