Help deciding if these keris are/were worth buying & for how much

[Disturbedone2004]

I am fairly new at buying & collecting keris and i need help deciding how much i should be willing to pay for these three items, one i already bought and just wanna know if i messed up. The bone handle one i bought for $250 US (mainly cause i loved the way it looked) the other two i told my friend that i am willing to pay up to $250 for but i don't know how much they are worth and this is where i need the help.

I appreciate any facts, opinions, insults, praises, whatever you wanna give me.

Thank you,
