i really have no idea what these items are worth

golden handaxe

+15 -5
armor penetrationt 20/19
+1 axe mastery 19/20

golden plagueborn sword
req9
+15 -5
cripled duration+33%
+7 vs. physical attacks

mods arent worth much, but they are replaceable

1. old skin 10-15k -new skin... not sure.. what does it look like?

2. 30-40k+
