Iron Halberd Swiss or German maybe, has celtic type cross in blade, need value?

 It appears all original and very old, perhaps a halberd celtic as the cross cut out in it implies, I am no weapons expert.  Nothing modern on it, even the decorations cut out in the iron are far from symetrical, it is about 6 1/2" feet in length. The spear point is about 8 inches long with a slight bent tip as if it could have penatrated armor maybe.  No cracks or stress cracks in iron. Hardwood handle and nails appear to be hand made.  The fabric tassles are very fragile almost like they could fall apart if handled roughly. 

Good
