japanese world war 2 bayonet what is the value?

very good shape

the value will greatly depend on its current state, whether it has someone's name/rank engraved on it (and whether you can locate that soldier's name/batallion/regiment, etc.), details on where it was acquired (battle details) and the potential interest of the buyer I have seen a couple over the years at flea markets and they usually sold for about $20-$25 (before major haggling). This does not mean yours is not worth much more but you will need to take it to an antique dealer to have it assessed
