It is not impossible to tell what the current value is - it's that what people are willing to pay for it, based on the current status and potential and species.
That means the value will be based on the trunks only. Branches are underdeveloped or absent, the wiring ads nothing to the value.
The first one seems to have nice tapering, the second one seems quite fat, but doesn't seem tapered.
Based on what I see on the photo I would probably want to pay 10-15 euro for the first one, 7,50 for the second one, max.
